Value Collection 4503 Hex Head Cap Screw M8 X 1.25

Product Description

The Value Collection 4503 is a metric hex head cap screw designed for general-purpose fastening in industrial, mechanical, and structural assemblies. Sized M8 x 1.25 with a 25 mm length under head, this screw is fully threaded along its entire shank. It is manufactured from Grade 8.8 steel, which provides a tensile strength suitable for medium- to high-load fastening applications. A zinc-plated finish adds a baseline level of corrosion resistance for indoor and light-duty environmental exposure. The 13 mm hex drive allows installation with standard hex wrenches or socket tools. This fastener conforms to JIS B1180-7 standards and is sold in packages of 50.

The 4503 hex head cap screw is suited for use in machinery assembly, equipment fabrication, and general metalwork where metric fasteners are specified. The fully threaded design makes it appropriate for use with a nut or in a through-hole application where thread engagement is needed along the full length of the fastener. It is commonly used by millwrights, machinists, maintenance technicians, and fabricators working in metric-standard environments.

Installation Notes

Installation is performed by mechanics, machinists, or maintenance technicians using a 13 mm wrench or socket. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound only when specified by the equipment manufacturer. Do not exceed the torque specification listed in the applicable equipment service documentation for Grade 8.8 M8 fasteners.
