Value Collection 40534 Set Screw 5/16-18 X 1 in Grade 8

Product Description

The VALUE COLLECTION 40534 is a Grade 8 alloy steel set screw with a knurled cup point, sized 5/16-18 x 1 inch overall length. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, gear, or pulley — onto a shaft by applying direct force at the point of contact. The knurled cup point bites into the mating surface to resist rotation and axial movement. Drive is provided by a 5/32-inch hex key. These fasteners conform to ASME/ANSI B18.3 and ASTM F912 standards and are appropriate for medium-to-high load clamping applications in mechanical assemblies.

These set screws are commonly used in HVAC equipment, pump assemblies, blower wheels, motor shaft collars, and general mechanical installations where a flush or recessed fastener is required. The Grade 8 alloy steel construction handles elevated clamping loads and resists deformation under torque. The UNC thread form (5/16-18) is a standard coarse thread widely used across industrial and commercial mechanical assemblies. This package contains 50 pieces, making it suitable for service stock or larger installation jobs.

Key Features

• Knurled cup point grips mating shaft surfaces to resist both rotation and axial slip
• Grade 8 alloy steel construction provides high tensile strength for demanding clamping applications
• 5/16-18 UNC coarse thread for broad hardware compatibility
• 5/32-inch hex key drive for recessed, torque-efficient installation
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Sold in a 50-piece pack for service inventory or multi-unit installations

Compatibility

Designed as a standard 5/16-18 UNC set screw replacement or service stock fastener for mechanical assemblies requiring a knurled cup point, Grade 8 alloy steel fastener in this thread size and length.

Installation Notes

Installation is performed by mechanical technicians using a 5/32-inch hex key or Allen wrench. Always de-energize and lock out the equipment before working on any rotating assembly. Ensure the mating shaft surface is clean and free of debris before seating the screw. Do not exceed the rated torque range for the thread size and material grade as specified by applicable mechanical standards.
