Value Collection 42340 Hex Head Cap Screw M12 X 1.25

Product Description

The VALUE COLLECTION 42340 is a metric hex head cap screw designed for general mechanical fastening applications requiring a fine-pitch thread. Built from Grade 8.8 steel with a zinc-plated finish, this fully threaded fastener measures M12 x 1.25 thread pitch with a 25 mm length under head. The 19 mm hex drive size accommodates standard metric wrenches. Manufactured to DIN 961 and ISO 8676 standards, it provides consistent thread geometry and tensile strength suited for machinery, automotive, and structural assembly work. Installation is performed by licensed trades or experienced mechanical technicians working within metric fastener specifications.

This screw is appropriate for metric-dimensioned assemblies where a fine-pitch M12 fastener is specified. Fine-pitch threads offer improved resistance to loosening under vibration compared to coarse-pitch equivalents at the same diameter, making this fastener a common choice in automotive drivetrains, industrial equipment, and precision machinery. The zinc-plated finish provides a baseline level of corrosion resistance for indoor or sheltered environments. Sold in packages of 50 units, it suits both production-line and maintenance-repair applications where moderate quantities are needed.

Key Features

• Fully threaded M12 x 1.25 fine-pitch metric thread per DIN 961 and ISO 8676
• Grade 8.8 steel construction for reliable tensile and yield strength in mechanical assemblies
• Zinc-plated finish provides baseline corrosion protection for dry or sheltered environments
• 19 mm hex drive accepts standard metric combination or socket wrenches
• 25 mm length under head suits medium-depth fastening applications
• Package quantity of 50 supports both maintenance stock and small production runs

Compatibility

Designed as an OEM-style replacement or direct-use fastener in any metric assembly specifying an M12 x 1.25 fine-pitch hex head cap screw conforming to DIN 961 or ISO 8676 standards.

Installation Notes

Installation is typically performed by mechanical technicians, millwrights, or automotive technicians using a metric wrench or socket sized to 19 mm. Always verify the mating thread is M12 x 1.25 fine pitch before installation, as fine and coarse M12 threads are not interchangeable. Follow the assembly drawing or equipment manufacturer torque specification for the Grade 8.8 fastener class. Inspect threads and seating surfaces for damage before torquing to final value.
