Value Collection 40536 Set Screw 5/16-24 X 3/8 in Grade 8

Product Description

The VALUE COLLECTION 40536 is a hex-drive set screw designed for secure, non-permanent fastening in mechanical assemblies where a flush or recessed connection is required. The knurled cup point bites into the mating surface to resist rotation and axial movement without the need for a through-hole or protruding head. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile and torsional strength suitable for demanding industrial and mechanical applications. Thread size is 5/16-24 UNF with an overall length of 3/8 inches, and it is driven with a 5/32-inch hex key. Each package contains 50 pieces.

This set screw is used in shaft-to-hub connections, collar retention, gear and pulley positioning, and similar mechanical fastening tasks across HVAC equipment assemblies, electrical motor mounts, pump housings, and general industrial machinery. The 5/16-24 UNF thread pitch is a fine-thread designation commonly found in precision mechanical components. The knurled cup point provides a positive grip on steel, aluminum, and other metal mating surfaces, making it a reliable choice for both original equipment assembly and field service replacement.

Key Features

• Knurled cup point grips mating surface to resist rotation and axial displacement
• Grade 8 alloy steel construction for high tensile and torsional strength
• 5/16-24 UNF fine-thread specification for precise engagement
• 5/32-inch hex key drive for installation in recessed or confined spaces
• Headless design sits flush or below the surface for clearance-sensitive assemblies
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 5/16-24 UNF headless set screw with a knurled cup point.

Installation Notes

Installation is typically performed by mechanical technicians or field service professionals using a 5/32-inch hex key or Allen driver. Ensure the mating bore and threads are clean and free of debris before installation. Do not exceed the torque capacity of the alloy steel fastener by using impact tools; hand or torque-wrench installation is recommended. Always de-energize and lock out equipment before servicing any mechanical assembly.
