About Threaded Studs and Rods

Quick-Release Pins for Access Panels

Attach these pins to a machine cover or access panel, then clip the panel on to an enclosure. Install them in a receptacle (sold separately). They're made of nickel-plated steel for good strength and some corrosion resistance.

Push-button pins lock in place until you push the button to release the spring-loaded retaining balls. A raised button has a narrow head to fit in small spaces. A recessed button prevents accidental pin removal. The head has a hole to add a ring and lanyard (sold separately).

Thread-In Receptacles for Quick-Release Pins

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.

Threaded Taper Pins

Tighten the nut to draw the pin out of the hole.

Metric

Threads on these pins stick out for easy removal from blind holes. Tighten the hex nut to draw the pin out. Often used for positioning components and securing assemblies, they taper at a uniform rate to fit in tapered holes. For a snug fit, use a tapered drill bit that matches the pin number for inch sizes or the small end diameter for metric sizes. They have slightly rounded edges to aid insertion.

Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.

Steel pins have good strength. Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions.

18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.

Length for metric pins measures the overall length, including the thread.

Knob-Style Retractable Spring Plungers

Knurled Knob

With Thread Locker

Without Thread Locker

Smooth Knob

Retract the nose by pulling the knob. These spring plungers have a long nose that provides a large bearing surface to handle side loads.

Knurled knob spring plungers provide a slip-resistant surface for controlled adjustment.

Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments. Black-oxide steel bodies resist corrosion in dry environments.

18-8 stainless steel is chemical resistant.

Plastic is chemical resistant and lightweight.

Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.

Spring plungers with thread locker have a locking patch that adds friction to resist loosening.

Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Sanitary Twist-to-Lock Knob-Style Retractable Spring Plungers

Without Sealing Nut

Replacement Sealing Ring

Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position. All of these plungers have a long nose that offers a large bearing surface to handle side loads. They’re often used for maintenance jobs.

Made of stainless steel, these plungers won’t corrode from frequent washdowns with harsh cleaners and sanitizers. All are self-draining with rounded edges and polished surfaces, so there are no crevices for bacteria to grow, reducing the chance of a foodborne illness. Seals block out water and keep contaminants from getting trapped in threads or grooves. They’re also bright blue, so you can easily spot broken pieces that fall into your line. The seals are FDA compliant for direct contact with food, but the lubricant is rated for incidental contact.

Slotted Long-Nose Spring Plungers

With Thread Locker

Without Thread Locker

Slotted on both ends for installation with a screwdriver. With a nose that is longer than a ball-nose, these provide a large bearing surface to handle side loads.

Steel is strong and wear resistant.

Plastic is chemical resistant and lightweight; acetal noses are extra soft to minimize marring soft surfaces such as aluminum.

Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.

Spring plungers with thread locker have a locking element that adds friction to resist loosening.

Long Hex-Nose Spring Plungers

With Thread Locker

Without Thread Locker

Fasten from the nose end with a wrench for more torque than slotted long-nose spring plungers. These spring plungers have a nose that is longer than ball-nose spring plungers to provide a large bearing surface and handle side loads. Made from wear-resistant steel, the body has a black-oxide finish to resist corrosion in dry environments.

Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.

Spring plungers with thread locker have a nylon locking pellet that adds friction to resist loosening.

Metric Partially Threaded Studs

Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. These studs are steel for strength and wear resistance. They’re best for dry environments, since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions.

Threaded Locating and Support Buttons

Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket. Threading makes these buttons easier to replace than press-fit, so they are a good choice for high-wear applications. They’re also known as rest buttons.

Threaded Spring-Loaded Guide Pins

Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications. A sealed top prevents debris from getting inside and making them seize up. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping.

Threaded Plug Gauges

These have a go gauge on one end and a no-go gauge on the other end. They allow you to inspect internal threads on parts. A taperlock handle lets you quickly replace worn gauges.

Check the minimum internal thread size with the go gauge end, and check the maximum internal thread size with the no-go gauge end. 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.

Threads have different classes of fit. Thread fit designates the tightness or looseness of mating threads. For example, inch threads with a 3B fit have tighter tolerances than threads with a 2B fit.

Threaded Plug Gauges with Calibration Certificate

These gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They allow you to inspect internal threads on parts. All have a go gauge on one end and a no-go gauge on the other end. A taperlock handle lets you quickly replace worn gauges.

Threads have different classes of fit. Thread fit designates the tightness or looseness of mating threads. For example, inch threads with a 3B fit have tighter tolerances than threads with a 2B fit.
