Value Collection -42186-3 M18 Hex Head Cap Screw 5-pack

Product Description

The VALUE COLLECTION -42186-3 is a fully threaded hex head cap screw built to metric standards for use in mechanical assemblies, structural fastening, and equipment maintenance. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw delivers a solid balance of tensile strength and corrosion resistance suited to general industrial and mechanical applications. The M18 x 2.50 thread size and 30 mm length under head make it a common choice for mid-to-heavy fastening tasks. The 27 mm hex drive allows for standard wrench engagement. This listing includes a package quantity of 5 screws.

This screw is used across a wide range of industrial, manufacturing, and field service applications wherever a metric fully threaded hex head fastener is required. It is appropriate for use in HVAC equipment mounting, pump and compressor assemblies, structural brackets, and general machinery fastening. The zinc-plated finish offers light to moderate corrosion protection, making it suitable for indoor and sheltered outdoor environments. Trade professionals including millwrights, pipefitters, HVAC technicians, and mechanical contractors will recognize this as a standard fastener for metric-spec equipment.
