The VALUE COLLECTION R88412329 is a 1/4-20 UNC hex head cap screw measuring 6 inches in length under head, manufactured from Grade 316 stainless steel with no surface coating applied. Partially threaded along the shank, this fastener is designed for applications where a smooth unthreaded shank provides clamping strength or clearance fit. Grade 316 stainless steel offers elevated corrosion resistance compared to 304 grade, making it suitable for harsh or moisture-prone environments. Licensed tradespeople, MRO professionals, and industrial maintenance technicians rely on this fastener type for structural and mechanical assembly work.
This hex head cap screw is used across a broad range of trade and industrial applications including HVAC equipment mounting, plumbing fixture support, pool and marine hardware, and general mechanical assemblies where corrosion resistance is a priority. The 1/4-20 UNC thread form is the most common unified coarse thread in the inch system and mates with standard 1/4-20 nuts, inserts, and tapped holes. Partial threading leaves a smooth shank section near the head for shear-load and alignment applications.
Designed as an OEM-style and general-use replacement or addition for any application requiring a 1/4-20 UNC hex head cap screw in Grade 316 stainless steel with a 6-inch length under head.
Installation should be performed by a qualified technician familiar with fastener torque requirements for the specific joint material and application. Always use a properly sized hex wrench or socket to drive the fastener and avoid over-torquing, which can yield the threads on smaller diameter screws. Ensure mating threads are clean and free of debris before assembly. In corrosive or submerged environments, verify that all mating hardware is also a compatible stainless alloy to prevent galvanic corrosion.
