Value Collection B10139 M12x1.75 Hex Socket Cap Screw 5pk

Product Description

The VALUE COLLECTION B10139 is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. The screw features an M12 x 1.75 metric thread profile with a 140 mm length under head. Constructed from alloy steel with a black oxide coating, it meets DIN 912 and ISO 898-1 fastener standards at material grade 12.9, indicating high tensile strength suited for demanding load-bearing connections. The internal hex drive accepts a standard hex key for installation in confined spaces where a traditional bolt head would not fit. This item is sold in a pack of 5.

This screw is used in general industrial fabrication, machine assembly, equipment maintenance, and structural connections requiring a flush or recessed fastener head. The M12 size and 140 mm under-head length make it appropriate for medium-to-heavy fastening tasks across a wide range of ferrous and non-ferrous assemblies. Machinists, millwrights, maintenance technicians, and mechanical contractors commonly stock this fastener for both production and field repair work. The black oxide finish provides modest corrosion resistance and reduces light reflection in finished assemblies.

Key Features

• M12 x 1.75 metric thread, partially threaded shank for controlled clamp load
• 140 mm length under head for deep-reach fastening applications
• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Black oxide coating for mild corrosion resistance and surface uniformity
• Internal hex drive compatible with standard metric hex keys and Allen drivers
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric socket cap screw for use in any application requiring an M12 x 1.75 thread pitch grade 12.9 fastener with a 140 mm under-head length.

Installation Notes

Installation is performed with a calibrated metric hex key or socket driver sized to the M12 socket cap screw drive. Always verify thread engagement depth and confirm the mating tapped hole meets grade 12.9 load requirements before final torque. Inspect threads for contamination or damage before assembly. Follow applicable machinery safety lockout and tagout procedures before disassembling or replacing fasteners in powered equipment.
