Value Collection R63093962 Slotted Spring Pin 420 Ss

Product Description

The VALUE COLLECTION R63093962 is a slotted spring pin manufactured from grade 420 stainless steel with a bright finish. Slotted spring pins, also called roll pins, are cylindrical fasteners with a longitudinal slot that allows radial compression during installation. This design creates a spring-loaded retention force inside the mating hole. The pin measures 1-1/4 inches in overall length and 5/16 inches in diameter. It is used in mechanical assemblies where vibration resistance and corrosion resistance are required. Machinists, millwrights, and maintenance technicians install these pins in production and field service applications.

Slotted spring pins of this type are common in shaft-to-component connections, linkages, hinges, and general mechanical assemblies across industrial, agricultural, and light manufacturing environments. The 420 stainless steel grade provides moderate corrosion resistance and higher hardness compared to austenitic grades, making this pin suitable for applications where wear resistance matters alongside basic corrosion protection. The bright finish indicates no additional coating or plating has been applied.

Key Features

• Grade 420 stainless steel construction for combined hardness and corrosion resistance
• Slotted design allows radial compression for self-retaining fit in drilled holes
• Bright finish — no plating or coating that could alter dimensional tolerances
• 1-1/4 inches overall length suits a wide range of standard mechanical assemblies
• 5/16 inches diameter for use in corresponding standard drilled or reamed holes
• Inch measurement system for compatibility with standard inch-dimensioned components

Compatibility

Designed as a standard slotted spring pin for use in any inch-dimensioned mechanical assembly requiring a 5/16-inch diameter roll pin hole and up to 1-1/4 inches of engagement depth.

Installation Notes

Slotted spring pins are driven into pre-drilled holes using a pin punch and hammer or an arbor press. Always ensure the hole diameter matches the nominal pin diameter per applicable tolerancing standards before installation. Wear appropriate eye protection during driving operations. Pins should not be reused after removal, as repeated compression cycling reduces retention force.
