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 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

Shoulder Screws

Shoulder Screws

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

Carriage Bolts

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

Set Screws

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

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

Tapping Screws

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

Tighten and loosen by hand without the need for tools

Wood Screws

Fasten material to wood or pieces of wood to each other

Elevator Bolts

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

Material Handling

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

Fabricating and Machining

T-Slot Bolts

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

Power Transmission

Rod Ends

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