Value Collection A410384 M4x0.7 Flat Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION A410384 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Manufactured from 316 austenitic stainless steel to Grade A4, it delivers strong corrosion resistance suitable for wet, marine, and chemically exposed environments. The screw features an M4x0.7 thread size, an overall length of 20 millimeters, and a 2.50 millimeter hex socket drive. The 90-degree flat head seats flush with or below the mating surface, making it a practical choice for assemblies where protrusion cannot be tolerated. This fastener conforms to DIN 7991 and is sold in a pack of 25.

This fastener is used across a broad range of industries including HVAC equipment assembly, plumbing fixture fabrication, electrical enclosure construction, pool and spa equipment, and general mechanical assembly. The Grade A4 stainless steel composition makes it well suited for outdoor, coastal, and submerged installations where standard steel fasteners would corrode prematurely. Machinists, maintenance technicians, and fabricators working with metric hardware will find this screw appropriate for light-duty panel and bracket work requiring a low-profile head.

Key Features

• 90-degree flat head seats flush with the mating surface for a clean, low-profile finish
• M4x0.7 metric thread conforms to DIN 7991 fastener standard
• 316 austenitic stainless steel, Grade A4, for strong corrosion resistance in wet and marine environments
• 2.50 mm hex socket drive for use with standard hex keys or Allen drivers
• Partially threaded shank for positive clamping and alignment
• Pack of 25 pieces supports small batch and production use

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M4x0.7 threaded holes in metal, plastic, and composite assemblies requiring a countersunk hex-drive fastener.

Installation Notes

Installation should be performed using a correctly sized 2.50 mm hex key or Allen driver to avoid rounding the socket. Ensure the mating countersink angle matches the 90-degree head profile before torquing. When installing stainless steel fasteners into stainless steel threads, apply an appropriate anti-seize compound to reduce the risk of galling. Follow applicable mechanical codes and equipment manufacturer specifications for torque requirements.
