Value Collection 199551 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 199551 is a partially threaded hex socket cap screw designed for secure fastening in applications where a recessed drive and high corrosion resistance are required. Built from 18-8 stainless steel, this fastener offers solid resistance to rust and oxidation in both indoor and outdoor environments. The 1/4-20 UNC thread size and 2-1/4 inches length under head make it suitable for medium-depth fastening tasks. A 3/16 inch hex socket drive allows precise torque application with standard Allen or hex key tooling. This screw is sold individually but requires a minimum order quantity of 100 units, making it appropriate for shop stock or production use.

This hex socket cap screw is commonly used in light mechanical assemblies, equipment enclosures, plumbing fixtures, HVAC component brackets, and general trade fabrication. The partial thread design provides clamping force at the head while allowing the unthreaded shank to align mating components. Stainless steel construction suits installations in damp or corrosive environments where carbon steel fasteners would deteriorate. Electricians, plumbers, HVAC technicians, and general contractors working with metal assemblies will find this a standard-stock fastener for a range of field and shop applications.

Key Features

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring an ANSI-inch threaded fastener of this size and drive type.

Installation Notes

Installation is performed with a 3/16 inch hex key or Allen-style bit driver. Ensure mating threads are clean and free of debris before driving the fastener. Do not use impact tooling on stainless steel socket cap screws, as galling of the threads can occur. Follow applicable mechanical or structural codes when fasteners are used in load-bearing assemblies.
