The VALUE COLLECTION R63038286 is a 3/8-24 hex head cap screw manufactured from 18-8 stainless steel. It measures 1-1/2 inches under the head and features a 9/16-inch hex drive. The 3/8-24 thread designation indicates a 3/8-inch nominal diameter with 24 threads per inch, conforming to the Unified National Fine (UNF) standard. This fastener is suited for mechanical and structural assemblies where corrosion resistance and precise thread engagement are required. Electricians, plumbers, HVAC technicians, and general contractors commonly use UNF cap screws when fastening equipment panels, brackets, or mounting hardware in environments exposed to moisture or mild chemicals.
This screw is appropriate for use in light industrial, commercial, and residential trade applications. The 18-8 stainless steel grade provides good corrosion resistance in wet or humid environments, making it a practical choice for HVAC equipment mounting, plumbing bracket assemblies, electrical enclosure hardware, and similar service work. It is sold individually but is subject to a minimum order quantity of 100 pieces, making it well suited for contractors and service shops maintaining shop stock of common fastener sizes.
Designed as a standard UNF hex head cap screw for use in any assembly requiring a 3/8-24 inch-series fastener in 18-8 stainless steel.
Install using a 9/16-inch hex wrench or socket driver. Verify that the mating thread is also 3/8-24 UNF before installation to avoid cross-threading. When fastening into dissimilar metals, be aware of potential galvanic corrosion concerns and use appropriate isolation hardware as needed. Always de-energize and isolate any equipment before accessing fastener locations on electrical or mechanical assemblies.
