Value Collection 42784 Hex Socket Cap Screw M12x1.75 45mm

Product Description

The VALUE COLLECTION 42784 is a fully threaded hex socket cap screw in M12 x 1.75 metric thread with a 45 mm length under head. Manufactured from alloy steel to material grade 12.9, it carries a black oxide finish that provides moderate corrosion resistance and reduces surface glare. The internal hex drive accepts a standard hex key or Allen socket. This fastener meets DIN 912 and ISO 898-1 standards, making it a recognized choice for mechanical assemblies, tooling fixtures, and structural joints where high-strength metric hardware is required. Installation is typically performed by machinists, millwrights, or maintenance technicians working on industrial or commercial equipment.

This screw is suited for demanding fastening applications across industrial machinery, hydraulic systems, fabricated steel structures, and equipment mounting. The 12.9 material grade indicates very high tensile strength, appropriate for joints subject to significant clamping load or vibration. The black oxide finish is compatible with oiled or lightly corrosive environments. It is sold individually with a minimum order quantity of 25 pieces per order, making it practical for service stock, maintenance kits, or production builds.

Key Features

• M12 x 1.75 fully threaded metric thread profile per DIN 912 and ISO 898-1
• 45 mm length under head for deep engagement in thick stock or flanged assemblies
• Alloy steel construction at material grade 12.9 for high clamping strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Internal hex socket drive compatible with standard metric hex keys and socket tooling

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M12 x 1.75 threaded bores in industrial machinery, fabricated assemblies, and equipment requiring grade 12.9 alloy steel fasteners.

Installation Notes

Installation requires a properly sized metric hex key or Allen socket driver. Always verify that the mating threaded bore is clean, undamaged, and matches the M12 x 1.75 thread specification before installation. De-energize or lock out equipment before fastener replacement on live machinery per applicable OSHA lockout/tagout procedures. Avoid over-driving; apply only the torque appropriate for the joint material and grade 12.9 fastener as specified by the equipment manufacturer.
