The VALUE COLLECTION 204182B is a 3/4-10 x 3-1/2 inch hex head cap screw manufactured from Grade 316 stainless steel. It features a unified national coarse (UNC) thread form and a 1-1/8 inch hex drive. Grade 316 stainless steel provides strong resistance to corrosion, pitting, and chemical exposure, making it well suited for wet, marine, and industrial environments. The 3-1/2 inch length is measured under the head. Machinists, pipefitters, millwrights, and maintenance technicians reach for this fastener when stainless-grade corrosion resistance is required alongside a standard coarse-thread fit.
This hex head cap screw is commonly used in HVAC equipment assemblies, pump and valve mounting, pipe flanges, and general industrial structural connections where moisture or chemical exposure would corrode carbon steel hardware. Its 3/4-10 UNC thread size is a standard heavy-duty fastener used across commercial and industrial mechanical systems. It is sold individually and is suitable for both new installation and maintenance replacement work.
Designed as a standard replacement or new-installation hex head cap screw for any application requiring a 3/4-10 UNC x 3-1/2 inch fastener in Grade 316 stainless steel.
Installation is performed by machinists, pipefitters, millwrights, or maintenance technicians using standard hand tools or power tools with a 1-1/8 inch socket or wrench. Verify that the mating threaded hole or nut matches the 3/4-10 UNC thread specification before installation. Apply anti-seize compound when joining stainless steel to stainless steel to prevent galling. Follow applicable equipment manufacturer torque tables or relevant codes for the specific joint type and load requirement.
