Value Collection -42729-2 M5x0.80 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42729-2 is a metric hex socket cap screw with an M5 x 0.80 thread and a 60 mm length under head. Manufactured from alloy steel at material grade 12.9, this fastener offers high tensile strength suited for demanding mechanical assemblies. The black oxide coating provides mild corrosion resistance and reduces light glare on exposed hardware. Partially threaded along its shank, the screw is designed for applications where a bearing surface under the head is required. It is driven with a standard hex key and conforms to DIN 912 and ISO 898-1 standards, making it a reliable choice for precision industrial and mechanical work.

This screw is used in a wide range of mechanical, industrial, and trade applications including HVAC equipment assembly, pump and motor mounting, structural brackets, and general machinery. The M5 x 0.80 metric thread size and partial threading make it appropriate for assemblies requiring controlled clamping load or where the unthreaded shank must pass through a clearance hole. This fastener is sold in multiples of 50 and is commonly specified by mechanical contractors, machinists, and maintenance technicians working with metric-fastened equipment.

Key Features

• M5 x 0.80 metric thread, partially threaded shank for precise clamping applications
• 60 mm length under head for deeper engagement in thick or stacked assemblies
• Grade 12.9 alloy steel construction for high tensile and yield strength
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Hex socket drive compatible with standard metric hex keys and Allen drivers
• 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 grade 12.9 partially threaded socket head cap screw.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated metric hex key or Allen driver sized for an M5 socket head fastener. Always ensure mating threads are clean and free of debris before installation. Do not exceed the rated grade 12.9 torque specification for M5 fasteners as defined by your applicable engineering standard or equipment service documentation. Confirm thread pitch compatibility with the receiving component before installation to avoid cross-threading.
