Fastening and Joining

Socket Head Screws

Socket Head Screws

With a deeper drive than flat and rounded head screws, these withstand more torque for a tighter hold

Flat Head Screws

Flat Head Screws

Fit in countersunk holes for a flush finish that won't snag on surrounding parts

Rounded Head Screws

Rounded Head Screws

Sit just above the surface for a low-profile finish and hold tighter than flat head screws

Hex Head Screws

Hex Head Screws

Used with nuts to create a stronger joint than flat and rounded screws

Shoulder Screws

Shoulder Screws

Rotate parts around the cylinder under the head to guide and align them during installation

12-Point Screws

12-Point Screws

12 contact points handle more torque than a hex head while a flange eliminates the need for a washer

Set Screws

Exert pressure at the tip to hold parts in place, unlike screws that hold material together with threads

Carriage Bolts

A smooth head provides a finished look while a square neck keeps the bolt in place when using a nut

Tighten and loosen by hand without the need for tools

T-Bolts

Turn by hand for easy fastening, use as a handle, or attach as a point for straps and clamps

Fastener Assortments

Keep a variety of common screws, nuts, and washers on hand

Wood Screws

Fasten material to wood or pieces of wood to each other

Hanger Bolts

Suspend pipe and other fixtures with wire or cable ties

Elevator Bolts

Create a flush joint to allow movement in tight spaces such as grain elevators and belting systems

Tapping Screws

Fasten a range of materials together without needing to tap the hole first

Studs

Press, weld, or screw in place to add a threaded fastening point

Binding Barrels

Binding Barrels

Create custom low-profile fasteners with binding barrel posts, caps, and screws

Threaded Rods

Anchor, connect, or hang components in a wide variety of applications

Thread Adapters

Thread Adapters

T-Handle Keys

To turn fasteners in hard-to-reach spots, there's a long shaft and a grip for your whole hand

Torque-Limiting Keys

Torque-Limiting Keys

Used to install carbide inserts in cutting tools, a handle limits the amount of torque generated

Nutdrivers

Tighten and loosen nuts and bolts

Fabricating and Machining

Setup Studs

Secure setup clamps and fixtures to your machine table or assemble heavy machines

T-Slot Bolts

Secure clamps and workpieces to machine tables with quicker setup than a T-slot nut and stud

T-Slot Nuts

Combine with setup studs or bolts to mount fixtures to machine tables

T-Slot Cleaners

T-Slot Cleaners

Scrape debris out of machine table T-slots

Fixture Clamps

Secure your workpiece to a fixture table so it won't move during machining

Power Transmission

Lead Screw Collars

Lead Screw Collars

Position components and limit travel along a lead screw

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

Die Spring Screw Caps

Die Spring Screw Caps

Brace springs and control tension in die sets while simplifying maintenance

Lead Screws

Pair with lead screw nuts to move components in a straight line

Ball Screw Nuts

Ball Screw Nuts

Internal ball bearings roll on ball screws for low friction when moving components

Material Handling

Hoist Rings

Pivot to resist stress that would bend or break an eyebolt when lifting at an angle

Eyebolts

Route rope through the loop or attach hooks and shackles for lifting

U-Bolts

Anchor heavy pipe, tube, and conduit; stronger than routing clamps and hangers

Building and Machinery Hardware

Cam Handles

For fast clamping, push down on the handle to draw two parts together
