Value Collection MP40465 Set Screw 8-36 X 1/4 in Grade 8

Product Description

The VALUE COLLECTION MP40465 is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies where a threaded fastener must bear against a shaft or mating surface without a protruding head. This screw features an 8-36 UNF thread, an overall length of 0.25 inches, and is manufactured from Grade 8 alloy steel for high tensile strength and resistance to fatigue. The cup point geometry creates a small indentation in the mating surface, providing reliable torque transfer and resistance to loosening under vibration. Installation requires a 5/64 inch hex key. Sold in a pack of 50.

This set screw is suited for use in light-duty mechanical and electromechanical assemblies, including motor shafts, collars, pulleys, and gear hubs found in HVAC equipment, pump assemblies, and general industrial machinery. The fine 8-36 UNF thread pitch offers precise engagement in thin-walled or close-tolerance tapped holes. Tradespeople, machine maintenance technicians, and OEM assemblers working on rotating equipment or drive components will find this a standard-stock fastener for routine service and new builds.

Key Features

• Cup point geometry creates a positive bite on shaft surfaces, resisting rotation and axial movement
• Grade 8 alloy steel construction provides high tensile and proof load ratings for demanding mechanical applications
• 8-36 UNF fine thread for precise engagement in tight-tolerance tapped holes
• 5/64 inch hex drive for installation with a standard Allen key or hex bit
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance
• Pack of 50 for shop stock or service kit replenishment

Compatibility

Designed as a standard headless cup point set screw per ASME/ANSI B18.3, suitable for any tapped hole with an 8-36 UNF thread specification requiring a 0.25 inch overall length fastener.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a 5/64 inch hex key or Allen bit. De-energize and lock out all rotating equipment before installing or adjusting set screws on shafts or collars. Do not exceed the rated torque range for the thread size and material grade as published in ASME standards. Inspect the mating shaft surface for damage after removal of an existing set screw before installing a replacement.
