Value Collection 015283PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The Value Collection 015283PR is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and trade assembly applications. It features a 3/8-24 UNF thread size with a 1/2 inch length under the head and is fully threaded from the bearing surface to the tip. The 5/16 inch hex drive accepts a standard Allen or hex key. Constructed from alloy steel with a black oxide finish, this screw offers solid tensile strength and moderate corrosion resistance in controlled environments. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for precision-fit assemblies where dimensional consistency is required.

This socket cap screw is a common choice in equipment maintenance, mechanical assembly, and structural fastening across HVAC, plumbing, electrical, and general industrial applications. The fine 3/8-24 UNF thread pitch provides greater holding strength in metal-to-metal connections compared to coarse thread equivalents. It is well suited for use in tapped holes in steel, aluminum, or cast iron components where a low-profile, recessed-drive fastener is preferred. Installation is typically performed by millwrights, maintenance mechanics, and trade technicians using a 5/16 inch hex key or Allen driver.

Key Features

• 3/8-24 UNF fine thread for strong metal-to-metal holding power
• Fully threaded shank — 1/2 inch length under head
• 5/16 inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides light corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 3/8-24 UNF fully threaded hex socket cap screw with a 1/2 inch length under head and 5/16 inch drive.

Installation Notes

Install using a calibrated 5/16 inch hex key or Allen driver to avoid rounding the socket. Always verify the receiving thread is clean and undamaged before installation. Follow applicable ASME or equipment manufacturer torque guidelines for 3/8-24 fasteners in the specific base material. De-energize and lock out any equipment before accessing fastened assemblies.
