Value Collection 015195PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 015195PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 5/16-18 UNC thread with full threading along its 1/2-inch length under the head. The alloy steel construction and black oxide coating provide corrosion resistance and surface hardness suited to demanding environments. Installation uses a 1/4-inch hex drive, compatible with standard hex keys and socket drivers. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for precision assemblies where dimensional and strength tolerances matter.

This screw is used across a wide range of trade and industrial applications including equipment mounting, machinery assembly, HVAC component fabrication, and general metalwork. The 5/16-18 UNC coarse thread provides reliable engagement in tapped steel or aluminum holes. The black oxide finish helps reduce galling and light surface oxidation in moderate-exposure environments. Machinists, millwrights, and field technicians commonly install this type of fastener wherever a low-profile cap head and internal hex drive are required to clear adjacent components.

Key Features

• 5/16-18 UNC coarse thread for reliable engagement in standard tapped holes
• Fully threaded along the 1/2-inch length under head for maximum thread engagement in short-grip applications
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide coating reduces surface corrosion and minimizes galling during installation
• 1/4-inch hex socket drive accepts standard hex keys and socket driver bits
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 5/16-18 UNC fully threaded fastener with a 1/4-inch internal hex drive.

Installation Notes

Install using a calibrated hex key or hex socket driver sized to 1/4 inch. Ensure the receiving tapped hole is clean and free of debris before threading. Do not over-torque alloy socket cap screws in aluminum or soft-metal tapped holes, as thread stripping can occur. Follow applicable ASME or equipment-manufacturer torque guidelines for 5/16-18 fasteners in the specific joint material.
