Value Collection 823004PS Flat Socket Cap Screw M3x0.5

Product Description

The VALUE COLLECTION 823004PS is a metric flat socket cap screw manufactured from 18-8 austenitic stainless steel (Grade A2) with a bright, uncoated finish. The 90-degree flat head seats flush with the mating surface when fully driven, making it well-suited for assemblies where a low-profile or flush exterior is required. The hex socket drive accepts a standard hex key for installation and removal. Fully threaded along its entire shank length, this fastener conforms to DIN 7991 standards. It is commonly installed by mechanical assemblers, maintenance technicians, and fabricators working with metric hardware in corrosion-sensitive environments.

This screw is used in light-duty metric assemblies across a range of industries including equipment manufacturing, instrumentation, and general fabrication. The M3x0.5 thread size and 6 mm overall length suit compact assemblies where clearance is limited and a flush fastener profile is necessary. Grade A2 stainless steel offers solid resistance to corrosion in mildly aggressive environments, making this fastener appropriate for both indoor and outdoor applications where carbon steel would be prone to rust.

Key Features

• 90-degree flat head seats flush with the work surface for a low-profile installation
• Hex socket drive size: 2.00 mm, compatible with standard metric hex keys
• Fully threaded shank provides maximum thread engagement across the full 6 mm length
• 18-8 austenitic stainless steel (Grade A2) offers corrosion resistance in mildly aggressive environments
• Bright, uncoated finish preserves dimensional accuracy and thread tolerances
• Conforms to DIN 7991 fastener standard for consistent metric interchangeability

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw with M3x0.5 threading, suitable for use in any application requiring a standard metric M3 hex socket flat head fastener.

Installation Notes

Install using a 2.00 mm hex key or hex bit driver; ensure the driver is fully seated in the socket before applying torque to avoid stripping. Confirm the receiving hole is countersunk to a 90-degree angle to allow the flat head to seat properly flush with the surface. Power down or de-energize any equipment before accessing fastened assemblies in live systems. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when installing into stainless or aluminum tapped holes.
