Value Collection R57700681 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700681 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and exert a radial force against the bore wall. This design creates a secure, vibration-resistant fit without requiring a precision-reamed hole. At 3-1/4 inches long and 1/2 inch in diameter, this pin is suited for medium-to-heavy-duty mechanical assemblies. Machinists, millwrights, and maintenance technicians install these pins in shafts, hinges, linkages, and machine frames where a removable yet secure locating or locking fastener is required.

This slotted spring pin is sized for inch-measurement assemblies and is appropriate for use in general industrial, agricultural, and OEM manufacturing applications. The 18-8 stainless steel construction provides good corrosion resistance, making it a practical choice for installations exposed to moisture, mild chemicals, or outdoor conditions. It does not meet military specifications and is intended for commercial and industrial use. Pins of this type are commonly pressed or driven into pre-drilled holes in mating components to align or retain shaft-mounted parts such as gears, collars, and couplings.

Key Features

• Slotted design allows radial compression for a secure interference fit in standard drilled holes
• 18-8 stainless steel construction offers corrosion and oxidation resistance
• 3-1/4 inch overall length accommodates medium-to-heavy-duty shaft and linkage assemblies
• 1/2 inch diameter suits common bore sizes in inch-measurement mechanical systems
• Reusable fastener design allows removal and reinstallation with standard pin punches

Compatibility

Designed as a commercial-grade slotted spring pin for use in standard inch-measurement bores across general industrial, OEM, and maintenance applications.

Installation Notes

Slotted spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving bore should be drilled to the nominal pin diameter per applicable ASME or manufacturer tolerances. De-energize and lock out any machinery before pin installation or removal. Avoid driving pins into hardened or brittle materials without confirming bore hardness compatibility.
