Value Collection 42729 M5x0.80 Hex Socket Cap Screw 50mm

Product Description

The VALUE COLLECTION 42729 is a partially threaded hex socket cap screw designed for precision fastening applications requiring high tensile strength. Built from alloy steel with a black oxide finish, this screw meets DIN 912 and ISO 898-1 fastener standards and carries a material grade of 12.9, indicating it is suited for high-stress assemblies. The M5 x 0.80 mm thread pitch and 50 mm length under head make it a common choice in mechanical, industrial, and equipment-assembly work. Installation requires a hex key or Allen driver. Sold individually, with a minimum order quantity of 50 pieces.

This fastener is used across a broad range of industrial and mechanical assembly applications, including HVAC equipment frames, pump and motor mounting, and general trade fabrication. The black oxide coating provides mild corrosion resistance and reduces light reflection in service environments. The partial threading allows engagement across varying grip lengths, which is useful when fastening components of different thicknesses. Mechanical contractors, pipefitters, and equipment technicians routinely stock M5 hex socket cap screws for field and shop use.

Key Features

• M5 x 0.80 mm thread size with 50 mm length under head
• Alloy steel construction at material grade 12.9 for high-strength applications
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Partially threaded shank for versatile grip-length fastening
• Hex socket drive compatible with standard Allen or hex key drivers
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a partially threaded M5 x 0.80 mm hex socket cap screw conforming to DIN 912 dimensional standards.

Installation Notes

Installation should be performed with a correctly sized hex key or Allen driver to avoid rounding the socket drive. Ensure mating threads are clean and free of debris before driving. Grade 12.9 fasteners should not be substituted with lower-grade hardware in high-load or safety-critical joints without engineering review. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
