Tapped Taper Pins
These internally threaded pins sit flush in an assembly. For easy removal from a blind hole, thread a screw into the pin and pull out. Often used for positioning components and securing assemblies, they taper at a uniform rate to fit in tapered holes. Use a tapered drill bit that matches the pin number for a snug fit. They have slightly rounded edges to aid insertion.
Pins meet ASME B18.8.2 specifications for material and dimensions.

Slotted Ball-Nose Spring Plungers
Install these spring plungers with a screwdriver—they're slotted on one or both ends. The ball nose rolls to minimize wear and allow parts to move in and out of position.
Steel is strong and wear resistant.
440C stainless steel is hard, wear resistant, and mildly chemical resistant.
18-8 stainless steel is chemical resistant.
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.
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.

Partially Threaded Studs
Use the unthreaded end as a pivot point, hinge, shaft, or locator pin. Made from 18-8 stainless steel, these studs are chemical resistant and may be mildly magnetic.

Steel Wood Screw Threaded Studs
These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures. Install with a stud driver or create wrench flats by threading two nuts onto the stud and jamming them together.
Black-oxide steel studs are mildly corrosion resistant in dry environments.
Zinc-plated steel studs resist corrosion in wet environments.

Choose studs with below-head projection for a stronger hold that uses the full strength of the fastener. Pass these studs through a hole and weld them in place.
Choose studs with above-head projection to weld the screw directly to the surface of the material for a smoother appearance.

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 hold work and prevent over torquing.

Also known as caulk-in anchors, these stay secure when there's not much material to hold. When installed, the cone expands the sleeve to hold it firmly inside the hole. To install, insert the anchor cone end first and use an installation tool to drive the sleeve over the cone. Then, insert a screw or threaded rod and tighten. Pull-out strength and shear strength values are 25% of the ultimate values.

Hex Head Removable-Bolt Anchors for Block and Brick
A hex head allows for a secure grip with a wrench. Also known as sleeve anchors, these have a sleeve that expands for a secure hold in block and brick. They're often used to hold steel and wood panels, doors, framing, and shelving. To install, tap the anchor into a hole and tighten the bolt to expand the sleeve. As you tighten, the nylon ring compresses to secure the fixture against the base material. Made from 18-8 stainless steel, they're chemical resistant and may be mildly magnetic. Pull-out strength and shear strength values are 25% of the ultimate values.

Removable-Screw Anchors for Drywall, Plaster, and Wood Paneling
A drilled hole is required for installation. Screws can be removed repeatedly without affecting the anchor. To install, tap the anchor into the material until flush. Insert a screw and turn it to expand the anchor. For high volume tasks, use the optional installation tool—it doesn't require any twisting. Pull-out strength and shear strength values are 25% of the ultimate values.

Tapped Rounded Machine Keys
Thread a screw through the tapped hole to pop these keys out of a keyway. When installed, they fill oval keyways completely, reducing stress on the key and shaft. Using them in a closed keyway keeps them from sliding along the shaft axis. The rounded ends make it easy to slide gears, hubs, and other components into place. To install, press them in to place. Use them for permanent or high-torque applications, or to replace a key in a worn keyway. Keys are made of steel.
Oversized keys create a tight fit. They conform to ANSI B17.1 Class 2 standards for dimensions and tolerances.

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.
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.

Stud Welding Systems
Join threaded studs and pins to steel and stainless steel with resistance welding that won't damage the opposite side of the material.
Threaded studs are for thin-gauge base materials. 18-8 stainless steel studs are more corrosion resistant than copper-coated steel studs.
