Value Collection FHS1XX0510-050BX M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0510-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. It features a 90-degree flat head with a hex socket drive, requiring a 3 mm hex key for installation. The fastener is manufactured from 316 austenitic stainless steel to Grade A4, providing strong resistance to corrosion and chemical exposure. The thread is M5x0.8, fully threaded along its 10 mm overall length, and conforms to DIN 7991 dimensional standards. Sold in a minimum order quantity of 50 pieces, this screw is suited for mechanical assemblies, enclosures, and equipment panels where a low-profile head is required.

This fastener is used in applications where the screw head must sit flush with or below the surface of the mating material. Typical uses include machine frames, brackets, fixtures, enclosures, and marine or wet-environment assemblies where 316 stainless steel is specified for its superior corrosion resistance compared to 304 grade. The DIN 7991 standard makes it directly interchangeable with other metric fasteners built to that specification. Mechanical contractors, industrial maintenance technicians, and fabricators commonly use this type of screw in both light and heavy-duty assemblies.

Key Features

• 90-degree flat head profile allows flush or countersunk seating in mating surfaces
• 316 austenitic stainless steel, Grade A4, provides high corrosion and chemical resistance
• M5x0.8 fully threaded shank over 10 mm overall length
• Hex socket drive requires 3 mm hex key for installation and removal
• Conforms to DIN 7991 dimensional standard for metric interchangeability
• Sold in multiples of 50 pieces per order

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M5x0.8 threaded holes in machinery, enclosures, brackets, and fabricated assemblies where a countersunk hex socket fastener is required.

Installation Notes

Install using a 3 mm hex key or hex bit driver; do not use an undersized key as it may strip the socket. Verify the mating material is countersunk to 90 degrees before seating the head flush. In corrosive or marine environments, inspect thread engagement and torque to the fastener manufacturer or design engineer specifications. Avoid mixing 316 stainless fasteners with dissimilar metals in highly conductive or electrolytic environments to reduce the risk of galvanic corrosion.
