Value Collection 534004PR Flat Socket Cap Screw M3x0.5

Product Description

The VALUE COLLECTION 534004PR is a metric flat socket cap screw manufactured from 12.9 grade alloy steel with a black oxide finish. The 90-degree flat head seats flush with or below the mating surface, making it suited for assemblies where a low-profile, countersunk fastener is required. Drive engagement is through a 2 mm hex socket. At M3x0.5 thread size and 6 mm overall length, this screw is a compact fastener used in precision mechanical assemblies. Installation is performed by licensed or experienced technicians and skilled tradespeople working in equipment fabrication, maintenance, and repair.

This fastener is used in metric-threaded applications requiring a flush or countersunk head profile. The 90-degree flat head conforms to DIN 7991, a widely recognized fastener standard for countersunk socket screws. Typical install scenarios include machine frames, panels, enclosures, and mechanical sub-assemblies where the fastener head must sit flush to avoid interference with adjacent components. The fully threaded shank provides consistent thread engagement across the full 6 mm length. This product is sold individually but is subject to a minimum order quantity of 100 pieces per order.

Key Features

• 90-degree flat head seats flush or countersunk for low-profile assemblies
• 12.9 grade alloy steel provides high tensile and proof-load strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• 2 mm hex socket drive for precise torque application in tight spaces
• Fully threaded shank maximizes thread engagement over the entire 6 mm length
• Conforms to DIN 7991 fastener standard for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or standard-service fastener for metric M3x0.5 threaded applications conforming to DIN 7991 specifications.

Installation Notes

Installation should be performed by qualified technicians familiar with metric fastener torque practices for 12.9 grade alloy steel. Before servicing any assembly, ensure the equipment is powered down and de-energized or depressurized as applicable. Use a calibrated 2 mm hex key or driver bit to avoid rounding the socket drive. Do not substitute inch-size hex drivers, as they will damage the metric socket geometry.
