Use these caps to hold components in place and protect shaft ends.

Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings.

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.

No groove required—these rings have teeth that firmly grip the bore.

Also known as castle nuts, secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance.

About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.

Also known as Keps and K Lock nuts, these locknuts have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance.

These stainless steel locknuts have good chemical resistance and may be mildly magnetic.

A conical washer acts as a spring to add tension between the nut and the material surface for easy installation and mild vibration resistance. These metric locknuts have a smooth rim to resist scratching materials when tightened.

Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle.

Teeth on the outside edge of these metric washers bite into the screw head and joint for a tight grip.

The teeth on these washers bite further into the screw head and joint than standard external-tooth washers to provide a stronger hold.

With a nylon insert that grips your threaded shaft or spindle without damaging its threads, these locknuts—also called shaft nuts—hold bearings, bushings, gears, and pulleys prone to vibration tightly in place.

Designed to remove and install dual wheels on trucks and trailers, these sockets have a hex recess for accessing lug nuts and a square recess to turn the threaded shafts found on inner wheels.

Remove and install dual wheels on trucks and trailers with the sockets in these sets.
