Value Collection A210199 Flat Socket Cap Screw M3x0.5 100pk

Product Description

The VALUE COLLECTION A210199 is a metric flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. Built to DIN 7991, it features a 90-degree flat head with a 2.00 mm hex socket drive and a partially threaded shank. The M3x0.5 thread and 25 mm overall length make it well suited for light-to-medium duty assemblies in corrosive or moisture-prone environments. Manufactured from 18-8 austenitic stainless steel meeting Grade A2, this screw provides reliable resistance to rust and chemical exposure without sacrificing mechanical strength. Sold in packages of 100.

These flat socket cap screws are commonly used in mechanical assemblies, equipment enclosures, pump housings, HVAC panel fabrication, and similar applications where a recessed fastener head is necessary to maintain a smooth surface or clear adjacent components. The partially threaded shank allows for controlled clamping in through-bolted joints. The metric M3x0.5 thread standard is standard across a wide range of imported and domestically manufactured components. Installers in HVAC, plumbing, and light industrial trades will find this fastener appropriate for stainless steel and mixed-metal assemblies where galvanic compatibility is a consideration.

Key Features

Compatibility

Designed as an OEM-style replacement or stock fastener for metric M3x0.5 countersunk hex socket applications conforming to DIN 7991. Suitable for use in stainless steel, aluminum, and other materials requiring a flush-mount flat-head screw in a metric assembly.

Installation Notes

Install using a 2.00 mm hex key or Allen driver rated for the required torque. Countersink the mating hole to 90 degrees to match the flat head geometry before installation. When fastening into stainless steel, use an anti-seize compound to reduce the risk of galling. Always shut down and de-energize any equipment before replacing or servicing fasteners on mechanical assemblies.
