Value Collection FHS1XX0308-050BX M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0308-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. It features a 90-degree flat head driven by a 2 mm hex socket key, allowing the head to sit flush with or below the mating surface when installed in a properly countersunk hole. The fastener is manufactured from 316 austenitic stainless steel, Grade A4, conforming to DIN 7991. Thread size is M3x0.5 with a full 8 mm threaded length. This screw is suitable for mechanical assemblies, equipment panels, and fabrications where corrosion resistance and a low-profile head are required.

This fastener is well suited for marine environments, chemical processing equipment, food service equipment, and outdoor assemblies where 316 stainless steel corrosion resistance is specified. The M3x0.5 metric thread and DIN 7991 standard make it a common choice in precision machinery, enclosures, and instrumentation panels. Licensed technicians and fabricators working to metric standards will find this screw appropriate for stainless assemblies requiring a countersunk, flush finish. Sold in a minimum quantity of 50 per order.

Key Features

• 316 austenitic stainless steel, Grade A4 construction for superior corrosion resistance
• 90-degree flat head profile seats flush in countersunk holes
• Hex socket drive accepts a 2 mm hex key for precise torque application in tight spaces
• Fully threaded M3x0.5 shank along the full 8 mm length
• Conforms to DIN 7991 fastener standard for metric compatibility

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M3x0.5 threaded applications requiring a 316 stainless steel, Grade A4 fastener with a 90-degree countersunk flat head.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a 2 mm hex key or hex socket driver. The mating material must have a properly sized 90-degree countersunk hole to achieve a flush seating of the head. Power down and de-energize any equipment before fastener replacement or panel disassembly. Do not overtighten stainless steel fasteners, as galling can occur; use appropriate anti-seize compound when required by the application.
