Value Collection MP42779 Hex Socket Cap Screw M12 X 1.75

Product Description

The VALUE COLLECTION MP42779 is an M12 x 1.75 hex socket cap screw designed for high-strength mechanical fastening in industrial, maintenance, and fabrication applications. Manufactured from alloy steel to a 12.9 material grade, this fastener delivers exceptional tensile strength suited to demanding bolted joints. The black oxide finish provides mild corrosion resistance and reduces light reflection on installed hardware. The screw measures 20 mm under the head and is fully threaded along its entire shank length. Drive type is internal hex, requiring a standard hex key or Allen driver for installation. Licensed maintenance technicians, machinists, and industrial assemblers are the primary users of this fastener.

This screw is commonly installed in machinery frames, equipment housings, hydraulic manifolds, and structural brackets where a high-clamp-load cap screw is specified. The M12 x 1.75 thread pitch is the standard coarse metric thread for 12 mm diameter fasteners, making it widely interchangeable across metric-designed assemblies. Full threading along the 20 mm shank length maximizes thread engagement in shallow bosses or thin through-member applications. It conforms to DIN 912 and ISO 898-1 standards, which define geometry, mechanical properties, and proof load requirements for metric socket head cap screws at the 12.9 grade.

Key Features

• M12 x 1.75 coarse thread, fully threaded shank, 20 mm length under head
• 12.9 alloy steel material grade — high tensile and proof load rating for critical bolted joints
• Black oxide coating for mild surface protection and low-reflectance appearance
• Internal hex drive compatible with standard hex keys and socket drivers
• Conforms to DIN 912 and ISO 898-1 dimensional and mechanical standards

Compatibility

Designed as a standard DIN 912 metric socket head cap screw suitable for use in any metric-threaded assembly specifying an M12 x 1.75 coarse-thread fastener at 12.9 material grade.

Installation Notes

Installation is performed with a properly sized hex key or hex socket driver rated for the torque requirements of a 12.9-grade M12 fastener. Always de-energize, depressurize, or otherwise render safe any equipment before replacing structural fasteners. Refer to equipment OEM torque specifications for the application, as no torque value is supplied with this fastener. Fastener reuse after yielding or thread damage is not recommended.
