Value Collection R63283449 Thumb Screw 5/16-18 Oval Head

Product Description

The VALUE COLLECTION R63283449 is an 18-8 stainless steel thumb screw with an oval head and 5/16-18 UNC thread. Designed for hand-tightening applications where tools are not practical or accessible, this screw is suited for panels, enclosures, fixtures, and equipment covers across HVAC, electrical, and light mechanical installations. The 18-8 stainless steel construction provides solid corrosion resistance in both indoor and moderately exposed outdoor environments. At 1-1/2 inches in overall length with a 0.70-inch head diameter and 0.78-inch head height, it fits standard 5/16-18 threaded inserts and tapped holes without shoulder engagement.

This thumb screw is a common fastener in trade and light industrial applications where frequent panel removal or adjustment is required. The oval head profile offers a comfortable grip surface for repeated hand operation. It is appropriate for residential and light commercial use in electrical enclosures, HVAC equipment access panels, control boxes, and similar assemblies where a tool-free fastening solution is needed. The without-shoulder configuration makes it compatible with standard through-hole and tapped-hole installations.

Installation Notes

Install by hand into a pre-tapped or insert-threaded 5/16-18 hole; no tools are required for normal operation. Ensure the mating thread is clean and free of debris before installation to prevent cross-threading. De-energize or shut down any equipment before servicing panels or covers secured by these fasteners. Do not over-torque if tools are used during initial installation, as stainless steel fasteners are susceptible to galling.
