Thread-In Quick-Release Pin Receptacles

Use a screwdriver to install these receptacles in a threaded hole. Use them to secure quick-release pins when you can't drill a through hole. They're made of 18-8 stainless steel for a balance of strength and corrosion resistance, and passivated for added protection against corrosion and oxidation.

Sanitary Retractable Spring Plungers

With rounded edges and polished surfaces, these spring plungers are free of nooks and crannies where dirt, water, and bacteria could collect. The seal on the base keeps contaminants off the threads and is bright blue, so you can easily spot broken pieces that fall into your line. A tug of the knob manually retracts the nose so you can do everything from positioning containers on an assembly line to locking mixing blades in place. Spring plungers are FDA compliant for direct contact with food.

316 Stainless Steel Nose—Won't corrode from frequent washdowns with harsh cleaners and detergents.

Twist-to-Lock—Free up both hands to adjust your workpiece or switch out parts without the plunger springing back and getting in the way. Pull back the handle and twist to lock the nose in its retracted position.

Quarter-Turn Quick-Change Fixture Clamps

Install these clamps into fixture plates, machine subplates, and tombstones to quickly swap components in or out of your machining setup. They lock or unlock with the turn of a knob. Since they locate while they clamp, you can accurately position components with repeatability of ±0.1".

For accurate positioning, use at least two sets of clamps and cam receptacles. Install receptacles into a base plate and clamps into a fixture plate. Line up the two plates, insert the clamps into the receptacles, then turn the knobs to secure your fixture in place. If you need more holding capacity, use additional clamps and receptacles.

Cam Receptacles

Thread In

Thread In—Thread-in receptacles have a threaded body for installation in a tapped hole. You hold them in place with the included nut, so they’re good for thin base plates.

Go/No-Go Threaded Plug Gauges with Handle

Speed up thread tolerance checks—the handle on these gauges gives you a good grip to quickly thread and unthread go or no-go gauges. Use these gauges to make sure nuts, tapped holes, and other parts fall within tolerance. All are precisely manufactured to confirm thread fit. If the plug gauges wear down, you can insert new ones (not included) onto the taperlock handle.

A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.

Go/no-go gauges have both a go gauge on one end of the handle and a no-go gauge on the other to speed up tests. Go gauges check the minimum internal thread size. No-go gauges check the maximum internal thread size.

Accuracy Certificate Traceable to NIST—Gauges with an accuracy certificate traceable to NIST include verification from the manufacturer that their thread sizes are within tolerance. The certificate is also known as a certificate of compliance or a short-form certification.

Calibration Certificate Traceable to NIST—Gauges with a calibration certificate traceable to NIST were calibrated in a lab. The certificate, sometimes called a test report or long-form certificate, details the tested measurements.

For Metric Class 6H Thread Fit—These metric-threaded gauges are class 6H, which is comparable to the fit of those with Class 2B Unified Standard.

For Thread Fit—Thread fit designates the tightness or looseness of mating threads.

Go/No-Go Left-Hand Threaded Plug Gauges with Handle

A go and no-go gauge in one, these gauges check that left-hand threads fall within tolerance. Use them to confirm thread fit for nuts, tapped holes, and other parts. The taperlock handle speeds up tests, giving you a good grip to thread and unthread each gauge end. It also lets you swap out worn gauges for new ones (not included) on either end.

The go gauge checks the minimum internal thread size, and the no-go gauge checks the maximum. A part is within tolerance if it’s easy to thread the go gauge but difficult to thread the no-go gauge more than two turns.

For Metric Class 6H Thread Fit—For metric threads, the higher the class number, the looser the fit. Class 6H is the metric standard and works for most applications.

For Thread Fit—Thread fit designates the tightness or looseness of mating threads.
