The VALUE COLLECTION 86853330 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. Built to Grade 8 steel specification, this fastener delivers high tensile strength suitable for demanding assembly and maintenance work. The 5/16-18 UNC thread pattern and 1-inch length under head make it a common size across industrial, HVAC, plumbing, and electrical enclosure work. A zinc-plated finish provides a baseline level of corrosion resistance for indoor and light-duty outdoor use. Sold in a package of 10, these screws are well suited for technicians who need reliable hardware on the job site or in the shop.
This hex head cap screw is used in a wide range of trade and light industrial applications including equipment mounting, panel assembly, bracket fastening, and general mechanical maintenance. The UNC 5/16-18 thread is one of the most common coarse-thread sizes encountered in HVAC equipment, electrical enclosures, and plumbing fixtures. The Grade 8 rating indicates a high-strength fastener appropriate for applications where standard Grade 5 hardware may be undersized for the load requirement.
Designed for use in any application requiring a 5/16-18 UNC fully threaded hex head cap screw with a 1-inch length under head. Suitable as a replacement or supplemental fastener in equipment assemblies, structural brackets, and panel mounting where Grade 8 strength is specified.
Installation is performed with a standard hex wrench or socket driver sized for a 5/16-inch hex head cap screw. Always confirm the mating thread is 5/16-18 UNC before installation to avoid cross-threading. De-energize and lock out equipment before replacing fasteners on live electrical panels or mechanical assemblies, in accordance with applicable OSHA lockout/tagout procedures. Do not exceed the rated load for Grade 8 hardware; substituting a lower-grade fastener in a Grade 8-specified joint is not recommended.
