The VALUE COLLECTION -30578-1 is a 1/4-20 hex head cap screw measuring 2.75 inches under the head, manufactured from Grade 316 stainless steel. Grade 316 stainless offers superior corrosion resistance compared to 304-series alloys, making it well-suited for wet, chemical, or marine environments where standard fasteners would deteriorate. The hex drive head accepts standard metric and inch-drive sockets and wrenches. This fastener follows inch-system thread standards with a 1/4-20 UNC thread form, a coarse-pitch designation common across a wide range of mechanical and structural assemblies. Installation is performed by general maintenance technicians, pipefitters, plumbers, and HVAC service professionals.
This cap screw is appropriate for use in residential and commercial applications where corrosion resistance is a priority. Typical install scenarios include equipment enclosures, pipe hangers, pump mounting, pool and spa equipment, and outdoor or coastal environments. It is a general-purpose inch-series fastener sold individually with a minimum order quantity of 100 pieces per order. Its all-stainless construction eliminates the need for supplemental coatings or plating in corrosive service conditions.
Designed as a general-purpose inch-series hex head cap screw suitable for any application requiring a 1/4-20 UNC thread and 2.75-inch grip length in stainless steel construction.
Installation requires a standard 7/16-inch open-end wrench, box wrench, or socket driver. Always verify the mating tapped hole or nut is also rated for stainless steel or a compatible alloy to avoid galling. Apply an anti-seize compound appropriate for stainless fasteners to reduce the risk of thread galling during installation or future removal. Shut down and de-energize any equipment before replacing structural or panel fasteners.
