Value Collection 307116PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 307116PR is a hex socket cap screw designed for fastening applications that require a recessed drive and a strong, corrosion-resistant finish. Manufactured from alloy steel and coated in black oxide, this screw measures 2 inches in length under the head and features a 5/16-18 UNC thread with a 7/32-inch hex drive. It is partially threaded, providing a smooth shank section for proper clamping force in mechanical assemblies. This fastener meets ASTM A574 standards, making it suitable for demanding industrial and trade applications. Installation is performed with a standard 7/32-inch hex key or Allen wrench driver.

This cap screw is commonly used in machinery, equipment fabrication, structural assemblies, and general mechanical work where a flush or recessed fastener head is required. The 5/16-18 UNC coarse thread pattern makes it a standard choice across a wide range of metalworking, HVAC equipment panels, electrical enclosures, and plumbing fixture assemblies. The black oxide finish provides mild corrosion resistance in interior and protected environments. Technicians and tradespeople across mechanical, HVAC, and industrial service disciplines will find this a reliable standard fastener for everyday service and installation tasks.

Key Features

• 5/16-18 UNC coarse thread pattern for broad compatibility with standard tapped holes
• 2-inch length under head with partial threading for solid clamping on thicker materials
• 7/32-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 specification for high-strength fasteners
• Black oxide coating provides mild corrosion resistance and a low-glare finish

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring an ASTM A574-compliant alloy steel fastener with a 2-inch length under head and partial threading.

Installation Notes

Installation is performed by a qualified tradesperson using a 7/32-inch hex key or socket bit. Always ensure the mating tapped hole is clean, undamaged, and properly aligned before driving the fastener. Do not overtighten; consult applicable torque specifications for 5/16-18 UNC alloy steel fasteners as defined by the relevant equipment manufacturer or industry standard. De-energize or shut down any equipment before accessing fastener locations inside live panels or pressurized assemblies.
