Value Collection FHS1XX0310-050BX M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0310-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications across mechanical, industrial, and fabrication assemblies. Manufactured from 316 austenitic stainless steel to Grade A4, this screw delivers strong corrosion resistance in wet, marine, and chemically exposed environments. The 90-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. Thread size is M3x0.5 with an overall length of 10 millimeters. Drive engagement is via a 2.00 mm hex socket. The fastener is fully threaded along its entire length and conforms to DIN 7991.

This screw suits metric assembly work in environments where corrosion resistance is a priority, such as marine hardware, food processing equipment, medical device frames, and outdoor enclosures. The Grade A4 316 stainless designation makes it appropriate for applications exposed to chlorides or moisture. Electricians, millwrights, fabricators, and precision assembly technicians commonly use this fastener when a low-profile, flush-mount connection is required in stainless assemblies.

Key Features

• 316 austenitic stainless steel, Grade A4 — high corrosion resistance in chloride and marine environments
• 90-degree flat head for flush countersunk seating
• 2.00 mm hex socket drive for precise torque application in tight spaces
• Fully threaded M3x0.5 shank, 10 mm overall length
• Conforms to DIN 7991 fastener standard
• Metric thread standard for compatibility with metric assemblies

Compatibility

Designed as an OEM-style metric replacement or new-installation fastener for any countersunk M3x0.5 threaded application requiring a DIN 7991 flat socket cap screw in 316 stainless steel.

Installation Notes

Install using a calibrated 2.00 mm hex key or hex socket bit. The mating hole must be countersunk to 90 degrees to allow the flat head to seat flush. De-energize and lock out any equipment before fastener work on live assemblies. Avoid mixing stainless fasteners with dissimilar metals in highly conductive or galvanically active environments to prevent accelerated corrosion.
