Fastening and Joining

Precision Clevis Pins

These pins combine the locking capabilities of a clevis pin with the precision diameter of a dowel pin for a tight fit.

Dowel Pins

Use these metal dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.

Pull-Out Dowel Pins

To remove these pins, thread a screw or tool into the tapped hole, then pull them out.

Vibration-Resistant Slotted Spring Pins

Interlocking teeth help these pins resist sliding when exposed to vibration. They have a slot that presses closed when the pins are inserted so they don't flex after installation.

T-Bolts with Collar

Also known as clamping pins, these bolts have a collar that slides along the shaft and can be welded in place to clamp work in place and prevent over torquing.

T-Bolts

Also known as tank-strap bolts, these T-bolts are commonly used with a band clamp or a strap to hold fuel tanks and other objects in place.

Steel Wood Screw Threaded Studs

These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures.

No-Strike Hole-Alignment Pins for Flange Bolt Holes

Turn the pin and the tapered shaft forces the two holes into alignment.

No-Strike Hex Head Alignment Pin Sets

The tapered shaft of these pins eliminates the need for hammering and prying when aligning flange bolt holes.

Plug Gauges

Wear-Recognition Go Plug Gauges

A black-oxide treatment on these go gauges shows wear patterns so you can tell when you need to calibrate or replace the gauge—use them to check to minimum hole diameter.

Wear-Recognition No-Go Plug Gauges

The black-oxide treatment on these no-go gauges shows wear patterns so you can tell when you need to calibrate or replace the gauge—they help you check the maximum hole diameter.

Wear-Recognition Plug Gauge Sets

To indicate when you need to calibrate or replace the gauges in these sets, gauges have a black-oxide treatment that shows wear patterns.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005".
