Value Collection 643255PS M12x1.5x40mm Hex Cap Screw 8.8

Product Description

The VALUE COLLECTION 643255PS is a metric hex head cap screw designed for general mechanical fastening applications requiring a fine thread pitch and high-strength steel construction. This screw features an M12 x 1.50 thread size with a 40 mm length under head and is fully threaded from the bearing face to the tip. Built to Grade 8.8 steel, it delivers a tensile strength appropriate for structural and industrial assemblies. The 19 mm hex drive allows engagement with standard metric wrenches and sockets. Compliance with DIN 961 and ISO 8676 standards ensures dimensional consistency across production batches.

This fastener is suited for use in machinery, fabricated metal assemblies, automotive components, and industrial equipment where a fine-pitch metric thread is specified. The fully threaded shank maximizes thread engagement across the full grip length, making it a practical choice in applications where threaded inserts, nuts, or tapped blind holes are used. The bright, uncoated finish is appropriate for indoor or controlled-environment installations where corrosion resistance is not the primary requirement.

Key Features

• M12 x 1.50 fine thread pitch per DIN 961 and ISO 8676 standards
• Grade 8.8 steel construction for high tensile and proof load performance
• Fully threaded shank for maximum thread engagement across entire grip length
• 19 mm hex head size compatible with standard metric wrenches and sockets
• Bright, uncoated finish for dimensional consistency and bare metal surface

Compatibility

Designed as a standard metric hex head cap screw for use in any application specifying an M12 x 1.50 x 40 mm DIN 961 or ISO 8676 fastener with Grade 8.8 steel and a fully threaded shank.

Installation Notes

Installation should be performed by a qualified mechanic or assembler using a properly sized 19 mm metric wrench or socket. Confirm that the mating thread in the nut or tapped hole matches the M12 x 1.50 fine thread pitch before assembly, as fine and coarse pitch fasteners are not interchangeable. Apply thread lubricant or thread-locking compound only when specified by the assembly drawing or equipment manufacturer. Follow applicable torque specifications provided by the equipment OEM or relevant industry standard for Grade 8.8 fasteners.
