Value Collection MP72092 Hex Socket Cap Screw 1/4-20 50pk

Product Description

The VALUE COLLECTION MP72092 is a hex socket cap screw designed for secure fastening in mechanical, industrial, and trade applications. This screw features a 1/4-20 UNC thread size, a 1/2-inch length under head, and is fully threaded throughout its shank. Drive engagement is via a 3/16-inch hex socket. Constructed from alloy steel with a black oxide coating, the MP72092 delivers solid tensile strength and corrosion resistance appropriate for general-duty installations. This package contains 50 screws, making it a practical stocking quantity for service vans, shops, or job-site inventory. Conforms to ASME B18.3 and ASTM A574 standards.

Hex socket cap screws of this specification are commonly used across HVAC equipment assembly, electrical enclosure mounting, plumbing fixture installation, and general mechanical assembly where a flush or recessed fastener head is required. The black oxide finish provides mild corrosion resistance suitable for indoor and controlled-environment applications. These screws are appropriate wherever a 1/4-20 UNC fully threaded cap screw with a 3/16-inch hex drive is specified by the equipment manufacturer or installation drawing.

Installation Notes

Install using a 3/16-inch hex key or hex socket bit driver. Ensure mating threads are clean and free of debris before installation. Do not overtighten, as alloy steel screws in softer base materials can strip threads; follow torque specifications provided in the equipment manufacturer's documentation. Black oxide-coated fasteners are intended for dry or low-humidity environments and should not be substituted for stainless or plated fasteners in wet or outdoor applications without engineering review.
