The VALUE COLLECTION -40866-1 is a 10-24 button socket cap screw designed for secure mechanical fastening in applications requiring a low-profile head. Manufactured from alloy steel with a black oxide finish, this screw measures 5/8 inches in length under the head and is fully threaded with a UNC thread standard. The hex socket drive accepts a 1/8-inch hex key for installation. Hardness is rated at 36-43 HRC, making it suitable for moderate- to high-strength fastening tasks. This package contains 50 screws. Installers and maintenance technicians working in industrial, mechanical, or trade-service environments will find this screw appropriate for standard assembly and panel-fastening work.
This button socket cap screw is suited for general mechanical assembly, equipment maintenance, and structural fastening where a low-profile button head is required to clear adjacent components. The 10-24 UNC thread is a common size across HVAC equipment panels, electrical enclosures, pump housings, and light mechanical assemblies. The black oxide finish provides mild corrosion resistance in indoor or protected environments. The 50-piece package supports job-site stock and service van inventory.
Designed as a standard 10-24 UNC button socket cap screw suitable for use in mechanical assemblies, equipment panels, and enclosures that accept a low-profile hex socket drive fastener in this thread size and length.
Installation is performed with a 1/8-inch hex key or hex-bit driver. De-energize or power down any equipment before accessing fastener locations on electrical enclosures or HVAC panels. Ensure thread engagement is sufficient and do not overtighten, as alloy steel screws can damage tapped holes in softer base materials. Follow applicable equipment manufacturer torque guidelines and relevant codes such as NEC or ANSI standards where required.
