Hillman Fasteners 831502 Hex Head Cap Screw 100 Pack

Product Description

The HILLMAN FASTENERS 831502 is a box of 100 stainless steel hex head cap screws sized 1/4-20 x 1/2 inches with coarse thread. These fasteners are designed for secure mechanical connections in applications where corrosion resistance is a priority. The 1/4-20 designation indicates a 1/4-inch nominal diameter with 20 threads per inch, a coarse thread pitch common in general mechanical and structural assembly. Hex head cap screws require a standard hex wrench or socket driver for installation. The stainless steel construction resists rust and oxidation, making this hardware suitable for both indoor and outdoor environments across trade applications.

These cap screws are used across HVAC, plumbing, electrical, and general mechanical installations where a reliable threaded fastener is required. Common applications include equipment panel mounting, bracket attachment, access door hardware, and equipment base connections. The 1/2-inch length and coarse thread pattern make them well suited for light to medium clamping tasks in metal and structural assemblies. Sold in a 100-count box, this pack supports both job-site stock and service vehicle inventory needs for trade professionals.

Installation Notes

Installation requires a standard hex wrench or appropriately sized socket driver. Ensure mating threads are clean and free of debris before driving to avoid cross-threading. Apply appropriate thread torque for 1/4-20 stainless hardware per the equipment manufacturer's specifications. In stainless-to-stainless applications, consider using an anti-seize compound to prevent galling during installation.
