Value Collection 42786 M12x1.75 Hex Socket Cap Screw 55mm

Product Description

The VALUE COLLECTION 42786 is a metric hex socket cap screw designed for high-strength mechanical fastening applications. This partially threaded fastener features an M12 x 1.75 thread size with a 55 mm length under head and is manufactured from alloy steel with a black oxide finish coating. Rated to material grade 12.9, it delivers high tensile and proof load strength suitable for demanding structural and machine assembly work. The internal hex drive accepts a standard hex key or Allen wrench. It conforms to DIN 912 and ISO 898-1 fastener standards, making it appropriate for precision-fit applications where dimensional consistency is critical.

This screw is suited for general industrial and mechanical assembly where grade 12.9 alloy steel fasteners are specified. Typical applications include machine frames, jigs and fixtures, hydraulic and pneumatic component mounting, and heavy equipment assembly. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it a common choice in both production and maintenance environments. Sold individually with a minimum order quantity of 25 pieces per order.

Compatibility

Designed as a DIN 912 and ISO 898-1 compliant metric hex socket cap screw suitable for M12 x 1.75 threaded applications requiring grade 12.9 alloy steel fasteners.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician using a calibrated torque wrench and the appropriate hex key size for M12 socket cap screws. Always verify thread engagement depth and confirm the mating component is rated for grade 12.9 fastener loads before final torque. Do not mix metric and unified thread fasteners in the same assembly. Follow applicable industry or equipment manufacturer specifications for torque and preload requirements.
