Value Collection 15205PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 15205PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. This fastener features a 5/16-18 UNC thread size with a 1-1/4 inch length under the head and is fully threaded along its entire shank. Driven with a 1/4 inch hex key, it is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a low-reflectance appearance. Machinists, millwrights, and maintenance technicians commonly install this screw type in precision and general industrial applications.

This screw is suited for use in machine frames, fixtures, jigs, equipment enclosures, and structural assemblies where a recessed drive and high clamping force are required. The 5/16-18 UNC coarse thread provides strong engagement in standard tapped holes and is widely used across industrial, manufacturing, and mechanical maintenance settings. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank for maximum thread engagement across the entire length
• Alloy steel construction provides high tensile strength and hardness
• Black oxide finish offers mild corrosion resistance and reduced surface glare
• 1/4 inch hex drive for use with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard-dimension hex socket cap screw for use in any application requiring a 5/16-18 UNC fully threaded fastener with a 1-1/4 inch length under head and a 1/4 inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/4 inch hex key or Allen driver. Ensure the receiving tapped hole is clean and free of debris before driving the fastener. Do not exceed the recommended seating torque for the alloy steel grade and thread size per applicable ASME standards. Inspect threads for damage before installation to avoid cross-threading or fastener failure.
