Value Collection 43179 Flat Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION 43179 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Conforming to DIN 7991, it features a 90-degree flat head driven by an 8 mm hex socket. The fastener is manufactured from 12.9 grade alloy steel, representing high tensile strength suitable for demanding mechanical assemblies. A black oxide finish provides mild corrosion resistance and reduces light reflection. The screw is fully threaded at M12x1.75 over an overall length of 40 mm. Installation and removal require a properly sized hex key or socket driver.

This screw suits metric mechanical assemblies where the fastener head must sit flush with or below the mating surface. Typical applications include machine frames, fixtures, tooling plates, brackets, and industrial equipment where a low-profile fastener is required. The 12.9 material grade supports high-clamp-load joints in both ferrous and non-ferrous assemblies. This item is sold individually but carries a minimum order quantity of 10 units.

Key Features

• 90-degree flat head profile seats flush in countersunk holes to eliminate head protrusion
• 12.9 alloy steel construction delivers high tensile and proof load ratings
• 8 mm hex socket drive for secure torque transfer with standard hex keys or drivers
• Fully threaded along the entire 40 mm length for maximum thread engagement
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a metric DIN 7991 flat socket cap screw for use in any M12x1.75 countersunk metric fastener application conforming to that standard.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench and an 8 mm hex key or socket bit. Ensure the mating countersink angle matches the 90-degree flat head geometry before installation. De-energize or lock out any equipment before fastener service in accordance with applicable OSHA lockout/tagout procedures. Do not mix metric and unified thread standards in the same assembly.
