The VALUE COLLECTION 209047C is a hex head cap screw sized 5/16-18 x 1-1/2 inches, manufactured from 18-8 stainless steel with a Unified National Coarse (UNC) thread standard. This fastener features a 1/2-inch hex drive head and measures 1-1/2 inches under the head. The 18-8 stainless steel alloy provides solid corrosion resistance, making it a practical choice for mechanical assemblies, equipment enclosures, and trade installations where moisture or chemical exposure is a concern. Licensed tradespeople across HVAC, plumbing, electrical, and general mechanical service work rely on standard inch-series fasteners like this for everyday equipment fastening tasks.
This screw is suited for light to medium-duty fastening applications in residential and commercial settings. Its 5/16-18 UNC thread engages standard tapped holes and nuts of the same thread specification. Common install scenarios include securing equipment panels, mounting brackets, junction boxes, and mechanical components where a corrosion-resistant fastener is preferred over zinc-plated or plain steel alternatives. The hex drive head accepts both open-end and box wrenches as well as socket drive tools for efficient installation in tight spaces.
Designed as a standard inch-series hex head cap screw for use wherever a 5/16-18 UNC fastener in 18-8 stainless steel is specified.
Install using an appropriately sized open-end, box, or socket wrench sized for a 1/2-inch hex head. Ensure the mating tapped hole or nut matches the 5/16-18 UNC thread specification before installation. Power down or de-energize any equipment before fastening components in electrical or mechanical enclosures. Do not over-torque stainless steel fasteners, as galling can occur — apply a thread lubricant or anti-seize compound when fastening into stainless or aluminum threads.
