Value Collection 151300PR Set Screw 5/16-24 X 5/16 in Grade 8

Product Description

The VALUE COLLECTION 151300PR is a flat point set screw designed for secure, non-marring clamping and locking applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, it delivers high tensile and torsional strength suited for demanding industrial and trade use. The screw features a 5/16-24 UNF thread with an overall length of 5/16 inches and is driven by a 5/32 inch hex key. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a specification-grade fastener appropriate for precision assemblies where thread engagement and point geometry must meet published tolerances.

This set screw is used in mechanical power transmission, shaft-to-hub connections, collar positioning, and fixture assembly across industrial, HVAC, plumbing, and electrical installation environments. The flat point style distributes clamping force across the mating surface without penetrating or deforming the shaft, making it well suited for hardened shafts or applications where the shaft must remain undamaged after fastener removal. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Flat point geometry prevents shaft deformation and allows repeated removal without surface damage
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 5/16-24 UNF thread for fine-pitch engagement and precise axial positioning
• 5/32 inch hex drive compatible with standard hex keys and hex-bit drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Fractional inch sizing for straightforward replacement in standard American fastener applications

Compatibility

Designed as a specification-grade replacement or service fastener for any mechanical assembly requiring a 5/16-24 UNF flat point set screw driven by a 5/32 inch hex key.

Installation Notes

Installation is performed with a 5/32 inch hex key or equivalent hex-bit driver; ensure the key is fully seated before applying torque to avoid rounding the drive recess. Power down or de-energize any equipment before accessing shaft collars, pulleys, or hubs that retain this fastener. Do not exceed the rated torque range for Grade 8 alloy steel set screws of this size as specified in the applicable ASME standard. Confirm thread engagement and point contact are correct before returning the assembly to service.
