The VALUE COLLECTION R64406688 is a hex socket cap screw with a 5/16-18 UNC thread and a 1/4 inch hex drive. It measures 1 inch in length under the head and is manufactured from 18-8 stainless steel with a bright uncoated finish. This fastener is designed for applications where corrosion resistance and reliable clamping strength are required. It is installed using a hex key or Allen wrench and is commonly specified by maintenance technicians, pipefitters, and mechanical tradespeople in both light industrial and commercial settings.
This screw is suited for general-purpose mechanical assembly, equipment mounting, and maintenance work where a recessed drive fastener is preferred for flush or near-flush seating. The 5/16-18 UNC coarse thread provides reliable engagement in tapped holes across a wide range of base materials. The 18-8 stainless steel construction makes it appropriate for environments with exposure to moisture or mild corrosive conditions, including HVAC equipment housings, plumbing fixture mounting, and similar trade applications.
Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring this thread size and drive type in 18-8 stainless steel.
Install using a 1/4 inch hex key or compatible Allen bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Do not over-torque stainless steel fasteners, as galling can occur without proper lubrication. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
