Value Collection A210278 Button Socket Cap Screw M5x0.80

Product Description

The VALUE COLLECTION A210278 is a metric button socket cap screw designed for applications requiring a low-profile head and a secure hex socket drive. Sized at M5x0.80 with a 30mm length under head, this screw is partially threaded and manufactured from 18-8 austenitic stainless steel (Material Grade A2), offering solid corrosion resistance in wet or outdoor environments. The 3mm hex socket drive allows installation with standard hex key tooling. Sold in a package quantity of 25, this fastener is well suited for mechanical assemblies, fixtures, and equipment where a flush or recessed appearance is preferred over a standard cap head profile.

This fastener is appropriate for light to medium-duty metric fastening applications across industrial, mechanical, and trade environments. The button head profile sits lower than a standard socket cap screw, making it a common choice when clearance is limited or aesthetics matter. The bright, uncoated finish is typical for stainless steel fasteners used in food-adjacent, marine-adjacent, or chemical-exposure settings where coating integrity is a concern. Installers in HVAC, plumbing equipment assembly, and general mechanical maintenance will find this size a common replacement in metric-threaded assemblies.

• 3mm hex socket drive compatible with standard hex key sets
• Thread Fit Class 4G and 6G per ISO 7380 fastener standard
• Bright, uncoated finish — no coating to chip, flake, or interfere with torque readings
• Package quantity of 25 per order unit

Compatibility

Designed as an ISO 7380-compliant metric button socket cap screw for use in any M5x0.80 threaded application requiring a low-profile head and hex socket drive.

Installation Notes

Installation is performed with a 3mm hex key or hex bit driver; use a calibrated torque wrench when assembly specifications require controlled clamping force. Confirm thread engagement depth in the mating component before final tightening to avoid stripping partially threaded engagement. Stainless-to-stainless fastening can be prone to galling — apply an appropriate anti-seize compound when threading into stainless steel tapped holes. Follow applicable mechanical assembly codes and equipment manufacturer guidelines for torque and fastener reuse policy.
