Value Collection 36869 Flat Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 36869 is a flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. It features an 82-degree flat head driven by a 3/8-inch hex socket and is fully threaded along its 2-1/2-inch overall length at a 5/8-11 UNC thread size. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance in indoor and light-duty outdoor environments. It meets ASME/ANSI B18.3 and ASTM F835 standards. Licensed tradespeople and experienced maintenance professionals are the typical installers for this class of fastener.

This screw is suited for general mechanical assembly, structural fixturing, and machine component fastening where a low-profile countersunk head is needed. The 5/8-11 UNC thread and alloy steel construction make it appropriate for medium-to-heavy-duty bolted connections in fabrication shops, manufacturing equipment, and similar industrial or trade environments. The black oxide finish reduces light reflection and provides a surface that accepts oil or wax post-treatment to improve corrosion resistance in controlled settings.

Key Features

• 82-degree flat head provides a flush countersunk profile when seated in a properly prepared bore
• 3/8-inch hex socket drive for use with standard hex keys or socket drivers
• Fully threaded along entire 2-1/2-inch length for maximum thread engagement flexibility
• 5/8-11 UNC thread form per ASME/ANSI B18.3 and ASTM F835 standards
• Alloy steel construction for higher strength than standard carbon steel fasteners
• Black oxide finish reduces glare and provides a base for oil or wax corrosion inhibitors

Compatibility

Designed as a standard-dimension UNC flat socket cap screw compatible with any tapped 5/8-11 threaded hole requiring an 82-degree countersunk flat-head fastener per ASME/ANSI B18.3 specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using a properly sized 3/8-inch hex key or socket drive. Ensure the mating countersunk bore is machined to an 82-degree included angle before seating the screw. Apply a thread-locking compound or anti-seize as required by the application and torque to values specified by the equipment manufacturer or applicable engineering standards. De-energize and lock out all equipment before performing any fastener replacement or maintenance work.
