Value Collection 35069 Slotted Spring Pin 5/16in X 1-3/4in 50pk

Product Description

The VALUE COLLECTION 35069 is a slotted spring pin engineered for secure fastening in mechanical assemblies where controlled retention force and easy installation are required. Manufactured from 1070/1090 alloy steel, this pin measures 5/16 inches in diameter and 1-3/4 inches in length. The black oxide finish provides a base level of corrosion resistance while reducing light reflection in precision assemblies. Slotted spring pins compress radially as they are driven into a hole, creating a spring-loaded grip that resists vibration-induced loosening. Machinists, maintenance technicians, and millwrights install these pins in production and repair applications.

Slotted spring pins are used wherever a removable or permanent fastening pin is needed in machinery, jigs, fixtures, hinges, and linkage assemblies across general manufacturing, agricultural equipment, material handling, and industrial maintenance environments. This 50-piece package suits bench stock replenishment, production runs, or field service kits where consistent pin diameter and length are required. The inch-measurement system makes these pins a direct fit for standard inch-dimensioned bored holes.

Key Features

• 1070/1090 alloy steel construction for high shear strength and spring-back performance
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• 5/16 inches diameter x 1-3/4 inches length for compatibility with standard inch-dimensioned bores
• Slotted design allows radial compression for vibration-resistant retention without adhesives
• Packaged in quantities of 50 for bench stock and production use

Compatibility

Designed as a general-purpose slotted spring pin for standard inch-dimensioned through-holes and blind holes in mechanical assemblies requiring a 5/16-inch diameter pin.

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 hole diameter should be bored to the appropriate tolerance for the pin diameter to ensure correct retention force. Always wear appropriate eye protection when driving pins manually. To remove, drive the pin through the bore with a punch of smaller diameter than the pin, or use a pin extraction tool.
