Value Collection C30979 Hex Head Cap Screw M12 X 1.25

Product Description

The VALUE COLLECTION C30979 is a metric hex head cap screw engineered for general industrial and mechanical assembly applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, this fastener delivers a reliable combination of tensile strength and corrosion resistance suited for moderate-duty environments. The M12 x 1.25 thread profile is a fine-pitch metric designation, providing greater resistance to vibration-induced loosening compared to coarse-pitch equivalents. At 30 mm under the head with full threading along the entire shank, this screw is suitable for through-hole and close-tolerance tapped applications. It conforms to DIN 961 and ISO 8676 standards. A licensed mechanic, millwright, or maintenance technician will typically install this fastener in machinery, automotive, or structural assemblies.

This screw is applied across a wide range of metalworking, mechanical maintenance, and light structural assembly scenarios. The fine-pitch M12 x 1.25 thread suits applications where vibration resistance or precision clamping is a priority. Full threading makes it practical for use with nuts across the full fastener length or for engagement into tapped holes where maximum thread contact is needed. It is sold in a package quantity of 10, appropriate for bench stock or job lot use in shop and field environments.

Key Features

• M12 x 1.25 fine-pitch metric thread for improved vibration resistance
• Grade 8.8 steel construction providing high tensile and yield strength
• Zinc-plated finish for basic corrosion protection in indoor and moderate-exposure environments
• Fully threaded shank for maximum thread engagement in tapped holes or with nuts
• 19 mm hex drive size compatible with standard metric wrenches and sockets
• Conforms to DIN 961 and ISO 8676 dimensional and mechanical standards

Compatibility

Designed as a standard DIN 961 and ISO 8676 compliant metric hex head cap screw, suitable for use in any M12 x 1.25 tapped hole or with a compatible M12 x 1.25 metric hex nut in industrial, automotive, and mechanical maintenance applications.

Installation Notes

Installation requires a 19 mm open-end, combination, or socket wrench. Verify that the mating thread in the tapped hole or nut matches the M12 x 1.25 fine-pitch specification before installation, as fine and coarse M12 threads are not interchangeable. Apply thread lubricant or thread-locking compound as dictated by the assembly specification. Follow the equipment manufacturer torque specifications for the fastened joint — do not rely on generic torque values without confirming the joint design requirements.
