Value Collection 42779 M12x1.75 Hex Socket Cap Screw 20mm

Product Description

The VALUE COLLECTION 42779 is an M12 x 1.75 metric hex socket cap screw designed for high-strength fastening in mechanical, industrial, and structural assemblies. Manufactured from alloy steel to material grade 12.9, this screw delivers exceptional tensile strength and is fully threaded along its 20 mm length under head. The black oxide coating provides moderate corrosion resistance and reduces light reflection in finished assemblies. Driven with a standard hex key or Allen wrench, this fastener is a go-to choice for machine builders, maintenance mechanics, and fabricators working to DIN 912 and ISO 898-1 standards.

This screw is suited for use in precision machinery, automotive components, hydraulic equipment, tooling fixtures, and general industrial fabrication where a high-strength, close-tolerance metric fastener is required. Its grade 12.9 alloy steel construction makes it appropriate for applications that demand higher clamping loads than standard grade 8.8 or 10.9 fasteners can provide. Minimum order quantity is 25 pieces per order increment.

Key Features

• M12 x 1.75 thread size with 20 mm length under head, fully threaded
• Grade 12.9 alloy steel construction for high tensile and proof load ratings
• Black oxide finish for moderate corrosion resistance and low-glare appearance
• Hex socket drive compatible with standard Allen keys and hex bit drivers
• Manufactured to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for any M12 x 1.75 threaded hole requiring a grade 12.9 alloy steel fastener.

Installation Notes

Installation is typically performed by maintenance mechanics or machine assembly technicians using a calibrated torque wrench and the appropriate metric hex key or socket bit. Apply thread engagement of at least 1.5 times the nominal diameter into the mating material for full load capacity. Inspect threads for contamination or damage before installation. Do not mix metric and inch-series fasteners in the same assembly.
