Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.

Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.

SAE washers generally have a smaller ID and OD than USS washers.

Reinforce holes in soft material to keep them from collapsing around screws.

Clipped to fit where standard washers can't, these won't rotate when you position the flat edge against a flat surface.

A slot in the side allows you to install and remove these washers without completely disassembling your joint.

Comparable to NORD-LOCK® and Sherex TEC Series washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting.

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Internal teeth dig into the screw head while the smooth outside edge won't snag objects. Use with metric fasteners that have small heads, such as fillister and cheese head screws.

The teeth on these washers firmly grip heads of 82° flat head countersunk screws.

These curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

These metal collars are stronger than plastic shaft collars.

Wider than standard shaft collars with twice the number of clamping screws, these ensure a better grip for greater holding power.

Two knurled sides provide micrometer-like movement for precise width adjustments.

An embedded sleeve squeezes the shaft as you tighten the clamping screws, allowing these collars to handle up to three times the thrust load of standard collars.

One side of these collars locks down like a standard one-piece shaft collar; the other has a flush face that's flat to 0.0005", which lets you mount the collars on a shaft next to precision bearings, sprockets, and gears.

Customize the bore of these collars to precisely fit your shaft.

Use a wrench to rotate your drive shaft without marring or gouging the shaft.

Although these collars fit inch-sized shafts, they have a metric OD and width for use with metric equipment.

Tighten the set screw to bite into an unhardened shaft for a secure hold.

Three tapped counterbored holes and three through-holes provide mounting flexibility.

These collars have two different sides—one locks down like a standard clamping shaft collar; the other has a flush face that you can machine to add slots, holes, and grooves to match your special setups.

Mount these collars flush against each other or attach components to either side—the round body has flattened ends with tapped holes.

Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft.

Slide these one-piece collars onto the end of your shaft to create an end-stop for linear components.

Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft.

Install these two-piece collars square shafts.
