Value Collection 88548441 Hex Cap Screw 1/2-13 X 1-1/2 in Grade 5 25pk

Product Description

The VALUE COLLECTION 88548441 is a fully threaded hex head cap screw designed for general mechanical assembly and structural fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable clamping strength and basic corrosion resistance in dry and mildly humid environments. The 1/2-13 UNC thread designation indicates a half-inch nominal diameter with 13 threads per inch, conforming to Unified National Coarse standards. The 1-1/2-inch length is measured under the head. This package contains 25 screws, making it practical for volume installation work.

This fastener is suited for use across mechanical, HVAC, plumbing, and electrical trade applications where a standard UNC hex head cap screw is required. The fully threaded shank allows engagement along the entire length, making it well suited for use with nuts or threaded inserts in thinner materials. Typical installation scenarios include equipment mounting, duct supports, panel fastening, and general structural assembly in both residential and light commercial settings.

Key Features

• 1/2-13 UNC thread — coarse pitch for fast engagement in standard steel, iron, and aluminum tapped holes
• Fully threaded shank provides maximum thread engagement across the full 1-1/2-inch length under head
• Grade 5 steel construction meets SAE J429 minimum tensile strength requirements for medium-strength fastener applications
• Zinc-plated finish provides basic corrosion resistance for indoor and protected outdoor use
• Inch measurement system with UNC thread standard — compatible with standard SAE tooling and hardware
• Sold in a 25-piece package for convenient volume use on the job

Compatibility

Designed as a standard 1/2-13 UNC fully threaded hex head cap screw suitable for use with any 1/2-13 UNC nut, threaded insert, or tapped hole conforming to Unified National Coarse thread standards.

Installation Notes

Installation is performed with a standard 3/4-inch hex wrench or socket, as is typical for 1/2-13 fasteners. Ensure mating threads are clean and free of debris before assembly to avoid cross-threading or galling. Do not exceed the rated torque for Grade 5 fasteners in the relevant application standard. Zinc-plated fasteners are not recommended for prolonged exposure to salt spray or highly corrosive environments without additional protection.
