Value Collection 42728 M5x0.80 Hex Socket Cap Screw Din 912

Product Description

The VALUE COLLECTION 42728 is a metric hex socket cap screw built for high-strength fastening applications. Sized M5 x 0.80 mm with a 40 mm length under head, this fastener is partially threaded and driven with a hex (Allen) key. It is manufactured from alloy steel with a black oxide finish coating and carries a material grade of 12.9, indicating very high tensile strength suitable for demanding mechanical assemblies. Machinists, maintenance technicians, and fabricators use this screw in precision equipment, tooling fixtures, and industrial machinery where a flush, recessed drive is required.

This screw is appropriate for use in residential and commercial mechanical assemblies, manufacturing equipment, jigs, and structural fixtures where metric fasteners conforming to DIN 912 and ISO 898-1 standards are specified. The M5 thread size and 40 mm under-head length suit mid-duty clamping and joining applications across a wide range of fabricated assemblies. It is sold in a package quantity of 1, with a minimum order quantity of 50 units.

Key Features

• M5 x 0.80 mm thread with 40 mm length under head for precise fitment in metric-dimensioned components
• Material grade 12.9 alloy steel provides very high tensile and proof load strength
• Black oxide finish coating offers mild corrosion resistance and reduced light reflection
• Partially threaded shank improves shear strength in through-bolted joints
• Hex socket drive allows torque application in recessed or space-constrained locations
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for use in any application specifying an M5 x 0.80 mm partially threaded socket head cap screw at grade 12.9.

Installation Notes

Installation is performed using an appropriately sized metric hex key or Allen driver; consult the assembly drawing for the correct torque specification for the joint material and grade. Ensure mating threads are clean and free of debris before driving. Grade 12.9 fasteners should not be substituted with lower-grade hardware without engineering review, as they are designed for high-load applications where proper torque values are critical to joint integrity.
