The VALUE COLLECTION R40638460 is a hex socket cap screw designed for secure fastening in applications where a low-profile, high-strength fastener is required. Threaded to 10-32 UNF specification, this screw measures 5/8 inches in length under the head and accepts a 5/32-inch hex drive. It is manufactured from 18-8 stainless steel, which provides corrosion resistance suitable for both indoor and outdoor service environments. Tradespeople and technicians across HVAC, plumbing, electrical, and general mechanical assembly use socket cap screws like this one where a standard Phillips or slotted driver cannot access the fastener head.
This screw is appropriate for light mechanical assemblies, equipment enclosures, control panel mounting, and similar applications where a fine-thread 10-32 UNF fastener is specified. The 18-8 stainless steel construction makes it well-suited for environments with moisture exposure or where galvanic compatibility with stainless hardware is required. It is a standard inch-series fastener used across residential and commercial trade work wherever compact, recessed-drive fastening is needed.
Designed as a standard 10-32 UNF hex socket cap screw for use in any application requiring a fine-thread, 18-8 stainless steel socket fastener of this size.
Install with a 5/32-inch hex key or Allen driver. Ensure the receiving hole is tapped to 10-32 UNF before installation. Do not overtighten stainless steel fasteners, as the material is susceptible to galling — apply appropriate anti-seize compound when torque retention is critical. Verify fastener material compatibility with mating components before use in corrosive or dissimilar-metal environments.
