Value Collection R50000232 Machine Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION R50000232 is a slotted round head machine screw designed for general-purpose fastening applications. It features a 5/16-18 UNC thread form — a coarse unified thread rated for reliable engagement in both tapped holes and threaded inserts — and measures 2-1/2 inches in length under the head. Constructed from alloy steel with a zinc-plated finish, this screw delivers solid mechanical strength alongside basic corrosion resistance for indoor and light industrial service environments. The slotted drive accepts a standard flat-blade screwdriver for installation and removal. No washer is included or integrated.

This machine screw is suited for mechanical assemblies, panel mounting, bracket attachment, and structural fastening tasks across HVAC, electrical, plumbing, and general trade applications. The 5/16-18 UNC thread pattern is widely used in light-to-medium load connections where a coarse thread provides fast engagement and reliable pull-out resistance. Sold individually, with a minimum order quantity of 100 units per order.

Designed as a standard 5/16-18 UNC slotted round head machine screw suitable for use in any application requiring this thread size, drive type, and length specification.

Installation Notes

Installation is performed with a standard flat-blade screwdriver sized to the slot width of the screw head. Always ensure the mating tapped hole or threaded insert matches the 5/16-18 UNC specification before driving. Power down or de-energize any electrical or mechanical system before inserting or removing fasteners within live assemblies. Do not overtighten — torque to the requirement specified by the assembly manufacturer.
