The VALUE COLLECTION MP92321 is a 5/16-18 hex head cap screw designed for general fastening applications in trade and industrial environments. It measures 1-1/4 inches under the head and features a 1/2-inch hex drive. Manufactured from 18-8 stainless steel, this screw offers solid corrosion resistance suitable for both indoor and outdoor use. The Unified National Coarse (UNC) thread form provides reliable thread engagement across a wide range of materials. Electricians, plumbers, HVAC technicians, and equipment installers commonly use fasteners of this type when assembling panels, brackets, equipment housings, or structural supports where corrosion resistance is a requirement.
This hex head cap screw is well suited for light structural and mechanical fastening in residential and commercial trade applications. It fits scenarios where a standard inch-series coarse-thread fastener is needed and where the installation environment may involve moisture, chemicals, or outdoor exposure. The 18-8 stainless steel grade is a common choice for HVAC curb connections, plumbing bracket mounting, electrical panel support hardware, and pool equipment installations where mild corrosive conditions are present.
Designed as a standard UNC inch-series hex head cap screw suitable for use with 5/16-18 tapped holes, hex nuts, and standard flat or lock washers across a wide range of trade and mechanical applications.
Install using a 1/2-inch socket or open-end wrench. De-energize any equipment and shut off relevant fluid or gas supplies before working on assemblies where this fastener is used. Anti-seize compound is recommended when threading stainless steel fasteners into stainless steel tapped holes to prevent galling. Follow applicable mechanical codes and equipment manufacturer specifications for proper torque guidance.
