Value Collection R57700405 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700405 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows the pin to compress during installation and exert a constant radial force against the hole wall. This design provides secure retention without adhesives or secondary locking hardware. At 0.25 inches in overall length and 3/32 inches in diameter, this pin is suited for compact assemblies where space is limited. Fabricated from 18-8 stainless steel, the pin offers good corrosion resistance for use in wet, humid, or mildly corrosive environments. Installation requires only a pin punch and hammer or an arbor press.

Slotted spring pins in this size range are commonly used in light machinery, instrumentation, fluid handling equipment, and general mechanical assemblies. They serve as hinge pins, pivot pins, locking pins, and alignment pins in both OEM manufacturing and maintenance-repair-overhaul applications. The 3/32-inch diameter and 0.25-inch length make this pin appropriate for thin-wall assemblies or small-bore bores where standard solid pins would not provide the needed compliance. Sold individually per package, with a minimum order quantity of 100 pieces.

Key Features

• Slotted design compresses on insertion for a secure interference fit without adhesives
• 18-8 stainless steel construction provides corrosion resistance in wet and humid service environments
• Compact 0.25-inch length suits thin-wall and space-constrained assemblies
• 3/32-inch diameter fits standard small-bore pin holes in light machinery and instrumentation
• Inch measurement system for compatibility with standard US fastener tooling and gauges

Compatibility

Designed as a standard slotted spring pin for general mechanical assemblies requiring a 3/32-inch diameter, 0.25-inch long roll pin in inch-system applications.

Installation Notes

Installation is typically performed by a machinist, maintenance technician, or assembler using a pin punch sized to the pin diameter and a hammer, or an arbor press for controlled insertion. Always ensure the receiving hole diameter matches the pin specification before driving to avoid bore damage. Remove any burrs from the hole entrance before installation. Do not reuse a slotted spring pin that has been removed, as repeated compression cycles reduce retention force.
