Value Collection 643971PS M12x1.5 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643971PS is a metric hex head cap screw designed for mechanical fastening applications where close-tolerance thread engagement is required. The M12 x 1.50 thread pitch is a fine-pitch metric designation conforming to DIN 961 and ISO 8676 standards. The fastener is fully threaded along its 20 mm length under head, features a 19 mm hex drive, and is manufactured from Grade 8.8 steel with a bright uncoated finish. Grade 8.8 indicates a medium-high strength carbon or alloy steel with a minimum tensile strength of 800 MPa. This screw is well suited for precision assemblies where a fine thread pitch improves clamping force and vibration resistance.

This fastener is used in general industrial, mechanical, and OEM assembly applications calling for metric fine-pitch hardware. The fully threaded body makes it appropriate for through-hole or thin-material fastening where full thread engagement along the entire shank is required. Typical installation environments include machinery, equipment frames, automotive assemblies, and structural mechanical connections that require metric DIN or ISO compliant fasteners. The uncoated bright finish is suitable for indoor or controlled environments where corrosion is not a primary concern.

Key Features

• Fine-pitch M12 x 1.50 thread per DIN 961 and ISO 8676 standards
• Fully threaded along the entire 20 mm length under head
• Grade 8.8 steel construction for medium-high tensile strength
• 19 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish — no coating thickness to account for in tight-tolerance fits

Compatibility

Designed as an OEM-style replacement or standard-stock metric hex cap screw for any application specifying an M12 x 1.50 x 20 mm fully threaded fastener per DIN 961 or ISO 8676.

Installation Notes

Installation is performed using a 19 mm open-end, box, or socket wrench. Always verify mating thread pitch before installation — M12 x 1.50 is a fine pitch and is not interchangeable with the M12 x 1.75 coarse-pitch standard. Follow equipment manufacturer torque specifications for Grade 8.8 fasteners of this size. Minimum order quantity for this SKU is 100 pieces; confirm required quantity before placing an order.
