Fastening and Joining

Hex Head Screws

Hex Head Screws

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

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

Rounded Head Screws

Rounded Head Screws

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

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

Shoulder Screws

Shoulder Screws

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

Tighten and loosen by hand without the need for tools

Carriage Bolts

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

Wood Screws

Fasten material to wood or pieces of wood to each other

Threaded Rods

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

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Single-End Studs

Single-End Studs

Use the unthreaded end as a pivot point, hinge, shaft, or locator pin

Rivet Nuts

Add threads to thin panels with access from only one side; also known as blind inserts

Weld Nuts

Weld to metal surfaces to add permanent threads

Standoffs

Threaded to separate or connect parts as well as position components in assemblies

Spring Plungers

Spring Plungers

Apply accurate, consistent pressure for positioning, indexing, and ejecting parts

Magnets

Attract or repel metal objects to hang, secure, or position them

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

Fixturing Kits

Everything needed to mount workpieces of different sizes to your machine table

Fixturing Clamps

Fixturing Clamps

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

Power Transmission

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Connecting Rods

Connecting Rods

Use with rod ends and swivel joints to link components in push/pull assemblies

Ball Screws and Nuts

Ball Screws and Nuts

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

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

Eye Nuts

Pair with bolts or threaded rod to lift and hang components

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
