Within the Design Standards & Engineering information section, find general information on Carr Lane product measurement standards, tolerances and information on engineering changes which may occur to improve the quality of our products.
As Carr Lane is a worldwide manufacturer of tooling components, we follow the International (ISO) standard for metric thread callouts rather than ANSI standards commonly used in the United States. This section of the site includes a conversion chart detailing the ISO thread designation compared to its ANSI equivalent to make purchasing our products easier for those more familiar with ANSI. Standard Drill Sizes are also detailed in a separate chart.
Carr Lane guarantees the quality of its products. Get the product information you need by browsing our design standards & engineering information below.

  • Inch & Metric Thread Standards
    Metric thread sizes are specified differently than inch thread sizes. Inch sizes are specified using the nominal major diameter and the number of threads per inch. For example, a 3/8-16 (coarse) thread has a 3/8" nominal major diameter and 16 threads per inch, while a 3/8-24 (fine) thread has the same nominal major diameter and 24 threads per inch.
    Metric thread callouts are fundamentally different because the thread pitch (distance between each thread, in mm) is specified instead of threads per inch or per mm. For example, an M10x1.5 (coarse) thread has a 1.5mm pitch, while an M10x1.25 (fine) thread has a 1.25mm pitch.
    To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads. For example, the thread "M10" automatically means a coarse pitch, while any added pitch callout, such as M10x1.25, specifies a non-coarse pitch. This method of designation has the major benefit that average citizens do not need to memorize pitches just to identify a coarse thread.
    Virtually all thread standards across the world use the ISO designation convention, including the German DIN and Japanese JIS standards. All except the ANSI standard, which so far still asks for a pitch callout on coarse threads, despite the confusion that it causes.
    Since Carr Lane does business all across the world, we follow the international (ISO) standard for metric thread callouts. Stating the pitch of a metric coarse thread would be incorrect and totally confusing everywhere else in the world. The following table shows the ANSI equivalent callout for each ISO thread size.

    Installation & Technical Information

    To minimize drill bending and maximize hole accuracy, mount drill bushings as close to the workpiece as possible while still allowing adequate chip clearance. The necessary clearance depends on workpiece material and chip stringiness. For example, cast iron, with fine chips requires about 1/2 times drill diameter for chip clearance. Materials that produce long, stringy chips, such as cold-rolled steel and aluminum, require at least one-drill-diameter clearance.

  • Toggle Clamps
    Carr Lane manufactures industry-leading Toggle Clamps designed for any application. Learn how our products work, definitions for holding capacity and clamping force and the differences between the six-basic toggle clamp action types offered by Carr Lane. It’s all below in our toggle clamps technical information section.

    Six Basic Action Types

    Carr Lane Toggle Clamps offer six-basic action types, including Horizontal-Handle and Vertical-Handle Hold Down Clamps, Plunger-Type Push/Pull Toggle Clamps, Toggle Edge Clamps,Latch Action Toggle Clamps and Squeeze-Action Toggle Pliers.


    Toggle-Action Principles

    A toggle clamp is a quick-acting mechanical linkage where two of the elements make up a toggle action. Actuating the clamp first moves it into position, then applies clamping force by compressing or stretching the linkage elements after contacting the workpiece, then positively locks it by moving the toggle action's center pivot past the centerline of the other two pivots, against a stop.


    Holding Capacity & Clamping Force

    The "holding capacity" listed for each toggle clamp refers to the maximum external force that clamp can safely resist in its locked position without incurring any permanent deformation. For hold-down clamps, holding capacity is measured with the spindle as close as possible to the handle, and will be less at the end of the clamping arm.


    Open Arm vs. Solid-Arm Clamps

    Open-arm hold-down clamps offer maximum flexibility and adjustability. Two flanged washers hold the spindle in place anywhere along the arm by tightening the jam nuts.

  • Modular Fixturing
    Get introduced to Modular Fixturing products by Carr Lane in our technical information section. Carr Lane offers three modular fixturing system sizes to accommodate a wide-range of workpiece sizes. Learn how to mount Carr Lane tooling plates on T-slotted tables, subplates, pallets & learn about our Grid Address System. It’s all below. Browse Carr Lane modular fixturing technical information below.

    Introduction

    What exactly is modular fixturing? In many ways modular fixturing is just like permanent fixturing, except for a few key differences. First, modular fixtures can be assembled entirely from reusable off-the-shelf components, without machining. Next, many modular components are adjustable and universal. Finally, specially designed tooling plates and blocks, with a standard grid pattern, are the foundation of a good modular system.

    Three System Sizes

    A good modular fixture system needs to accommodate a wide range of workpiece sizes. Only Carr Lane offers a full line of modular components in three system sizes (Mini, Standard & Heavy). As a comparison to choose the proper system size, the table above shows typical clamping force exerted by clamp straps in each size (2-to-1 lever ratio).

    Multi Purpose Holes

    Every multipurpose hole on a tooling plate or block has a precision alignment bushing on top, with a threaded insert below it. Multipurpose holes will accept Locating Screws, socket-head cap screws, studs, and many other threaded components. The proper mounting screw for each component is listed in its table of dimensions. Locating screws are used to locate and fasten at the same time.

    Grid Address System

    The grid pattern of multipurpose holes on every tooling plate and tooling block face is labelled with letters in one direction and numbers in the perpendicular direction. Tooling-block faces are numbered (counterclockwise) with Roman numerals. This allows recording the mounting-hole location of each component as part of permanent documentation.

    Bushing & Threaded Inserts for Custom Tooling Plates

    These precision bushings and threaded inserts can be used to build your own custom modular tooling plates. When used together, the bushing and threaded insert will create a standard multipurpose hole.

    Mounting Tooling Plates on T-Slotted Tables

    Standard and heavy Rectangular Tooling Plates are accurately located on T-slotted tables using two Locating Keys in the center table slot. These plates are fastened to the machine table using four or six socket-head cap screws and T Nuts. Swivel Hoist Rings are recommended for lifting large tooling plates.

    Mounting Tooling Plates on Subplates

    All Rectangular Tooling Plates can be mounted as quick-change fixture plates on a subplate, as well as directly on a T-slotted machine table. Instead of the Locating Keys and Sure-Lock Fixture Keys used above for two-axis location, Subplate Locating Keys are used for three-axis location. A round key and a diamond (relieved) key are used together for precise location without binding. The subplate hole pattern shown here allows mounting any size and combination of standard or heavy Rectangular Tooling Plates, either lengthwise or widthwise.

    Mounting Tooling Plates & Block on Pallets

    JIS-type mounting is the most-common way to mount tooling plates and blocks on a machining-center pallet. Here the plate or block is located from two precisely ground reference edges at 90° to each other. The plate or block is pulled against the pallet's edge locators using three socket-head cap screws and also fastened down with four to eight socket-head cap screws, depending on the size. Swivel Hoist Rings are recommended for lifting tooling blocks and large tooling plates.

    Carr Lane Ball Lock Pins are high-strength, quick-release pins featuring a precision ground shank. Get strength data for all Carr Lane Ball Lock Pin products in this section.
  • Threaded Insert Technical Information
    Key-locking threaded inserts are ideal for thread reinforcement, especially when the mating stud or bolt will be removed frequently. They provide strong, permanent steel threads in a weaker parent material — ferrous, non-ferrous, or non-metallic. Key Inserts are also well suited for quick repair of stripped, damaged, or worn threads. A solid version is also available to use as a handy plug to relocate holes drilled or tapped on the wrong location.
  • Carr Lock® Technical Information
    Turning the clamping screw with a hex wrench advances the large center ball, pushing the three clamping balls outward. Within the Carr Lock® System, balls engage the angled ID of the Receiver Bushing, pulling the entire unit firmly downward.
  • Adjustable Locking Hubs Technical Information
    When adjustable locking hubs are in locked position, the locking-pin hub and release-pin hub are positively engaged by high-strength locking pins. When the release button is pressed, against spring force, push pins force the locking pins to disengage. The hub is now free to rotate. After reaching the desired angle, releasing the button again allows the locking pins to extend back into locked position.
