Value Collection 35094 Slotted Spring Pin 3 in 1/2 in Alloy Steel

Product Description

The VALUE COLLECTION 35094 is a slotted spring pin engineered for use in mechanical assemblies where a resilient, interference-fit fastener is required. Measuring 3 inches in overall length and 1/2 inch in diameter, this pin is manufactured from 1070-1090 alloy steel and finished with a black oxide coating for corrosion resistance. The slotted design allows the pin to compress on insertion and exert outward spring force against the bore wall, creating a secure hold without adhesive or additional hardware. Machinists, millwrights, and maintenance technicians install this type of pin in shafts, linkages, and housings across a wide range of industrial and mechanical applications.

This slotted spring pin is suited for use in general industrial equipment, agricultural machinery, material handling systems, and light manufacturing assemblies. It is appropriate for both original equipment manufacture and field repair situations where a standard inch-series slotted spring pin is required. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. It does not meet military specifications, making it appropriate for commercial and industrial applications rather than defense or mil-spec procurement.

Key Features

• Slotted design provides radial spring force for a secure interference fit in drilled bores
• 1070-1090 alloy steel construction offers good toughness and shear strength for mechanical fastening
• Black oxide finish adds corrosion resistance and a low-reflectance surface
• Inch-series dimensions: 3 inches long, 1/2 inch diameter
• Sold in a package quantity of 15 pins per order

Compatibility

Designed as a standard inch-series slotted spring pin for use in any drilled bore application requiring a 1/2 inch diameter, 3 inch long compression pin in a commercial or industrial assembly.

Installation Notes

Slotted spring pins are installed by licensed machinists, millwrights, or maintenance technicians using a pin punch and hammer or a hydraulic press. The receiving bore should be drilled to the appropriate tolerance for the pin diameter before installation. Ensure the assembly is fully de-energized and depressurized before servicing any components that retain this pin. Do not reuse a pin that has been driven out, as repeated compression cycles can reduce spring retention force.
