Value Collection 88547013 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 88547013 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance and reduces galling during installation. It carries a 1/2-13 UNC thread and measures 2.5 inches in length under head with partial threading. The 3/8-inch hex drive allows reliable torque transfer using a standard Allen key or hex bit driver. It is a go-to fastener for machinists, millwrights, and maintenance mechanics working on equipment where a low-profile, high-clamp-load connection is required.

This cap screw is suited for use in general industrial fabrication, machine frames, fixture building, and equipment maintenance where a socket-drive fastener is preferred over a hex head. The partial threading engages the mating thread over a defined grip length, making it appropriate for through-bolted and tapped-hole applications alike. Each package contains 3 screws, making it practical for small-quantity repair and replacement work on the shop floor or in the field.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard inch-series tapped holes
• 2.5 inch length under head suits moderate to deep grip-length requirements
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 3/8-inch hex drive accepts standard Allen keys and hex socket bits
• Partially threaded shank maintains shank strength in the unthreaded grip zone

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any tapped or clearance-hole application requiring a 1/2-13 UNC thread and socket-drive fastener.

Installation Notes

Installation is performed with a 3/8-inch hex key or socket driver; ensure the drive tool is fully seated before applying torque to prevent cam-out or drive rounding. Verify the mating thread is clean and free of debris before driving the screw. Always consult applicable fastener standards for torque specifications based on grade, coating, and lubrication conditions. Do not exceed the rated clamp load for the joint material or thread insert being used.
