Value Collection 42783 M12x1.75 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 42783 is a fully threaded hex socket cap screw designed for high-strength mechanical fastening applications. It carries an M12 x 1.75 thread profile with a 40 mm length under the head and is manufactured from alloy steel to material grade 12.9, one of the highest strength grades for metric fasteners. The black oxide finish provides a measure of corrosion resistance and reduces light reflection in precision assemblies. Installation requires a hex key or Allen driver. This fastener suits maintenance professionals, millwrights, and mechanical contractors working on equipment assemblies, machinery, and structural components.

The 42783 is applicable across a wide range of industrial and trade installations where a compact, low-profile cap screw head is required in confined clearance areas. Fully threaded along the entire shank length, it is well suited for through-hole or short-grip-length clamping situations. Common use cases include equipment mounting, bracket fabrication, and mechanical assembly work encountered in HVAC equipment, plumbing infrastructure supports, electrical panel framing, and general plant maintenance. The DIN 912 and ISO 898-1 standards govern the dimensional and mechanical requirements for this fastener.

Key Features

• M12 x 1.75 thread size with 40 mm length under head for precise grip-length control
• Grade 12.9 alloy steel construction delivers high tensile and proof-load strength
• Fully threaded shank maximizes thread engagement in short clamping applications
• Black oxide coating provides mild corrosion resistance and a low-glare finish
• Hex socket drive allows torquing in recessed or tight-clearance locations
• Manufactured to DIN 912 and ISO 898-1 dimensional and mechanical standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M12 x 1.75 threaded holes in machinery, equipment frames, and structural assemblies requiring a grade 12.9 fastener.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a properly sized hex key or torque wrench with the correct metric hex bit. Always verify thread engagement depth and mating material compatibility before final torquing. Inspect threads for damage or contamination before installation, and apply thread lubricant only if specified by the equipment manufacturer. Minimum order quantity for this SKU is 25 pieces.
