Spring Locating Pins


Zinc-Plated Steel Head	Acetal Head

As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping. Press into a drilled hole using the installation tool (sold separately). Also known as spring locating pins and side-thrust pins.

Acetal Head—Acetal-head pins won't mar soft metal and polished surfaces.

Create-Your-Own Spring Locating Pins

Thread in a screw, handle, or other part to create the right size and shape guide pin for your application. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping. Press into a drilled hole using the installation tool (sold separately).

Vibration-Damping Grommets


Style 1	Style 2

Press these slim, flexible grommets into a hole when space is too tight for a sandwich mount. They block vibration around sensors and other parts you count on for precise movements, strong signals, and accurate readings. The rubber stem and two flanges line the inside and both faces of a hole so no vibration can flow between the fasteners and mounting surface.

TPR Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.

Ribbed Vibration-Damping Washers

These washers add a rubber buffer between fasteners and mounting surfaces so vibration doesn't flow through and cause damage. They're often used to mount sensors, circuit boards, and other sensitive electronic components. To absorb more vibration, stack two washers together.

TPR Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

Vibration-Damping Bushings

Style 2

These bushings have a taller profile than vibration-damping grommets, so they can be used in thicker panels. With only one rim, they're also easier to install. They isolate vibration around motors, fans, blowers, and actuators to extend part life and minimize downtime.

TPV Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.

Sealed Spring Locating Pins

Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping. Press into a drilled hole using the installation tool (sold separately).

Stainless Steel Head—Stainless steel pins are a good choice to avoid corrosion when working with stainless steel workpieces or fixtures.

Ribbed Vibration-Damping Bushings

Style 1

The ribs flex to absorb slow, rumbling vibrations better than smooth rubber bushings. Install these bushings around shafts, large fans, and other slow-rotating components to extend part life and minimize downtime. Pair a ribbed vibration-damping washer with a bushing to absorb more vibration.

Multipurpose Neoprene—Resist wear and tear well enough for most applications. They are UV resistant and won't break down when exposed to oil, grease, and gasoline, so they're a good choice for motors and pumps.

TPR Rubber—The choice for outdoor use, these mounts protect precision bearings and other fine-tuned parts from vibration through a bad storm or deep freeze.

Chemical-Resistant PVC—Keep their flexibility when exposed to coatings, lubricants, and cleaning agents, such as the sodium hydroxide used in detergents.
