Value Collection A210279 M5x0.80 Button Cap Screw 25pk

Product Description

The VALUE COLLECTION A210279 is a metric button socket cap screw designed for fastening applications requiring a low-profile head and a secure hex socket drive. Sized at M5x0.80 with a 35mm length under head, this partially threaded fastener is manufactured from 18-8 austenitic stainless steel (Material Grade A2), providing solid corrosion resistance in wet or humid environments. The bright, uncoated finish maintains dimensional accuracy and allows for straightforward inspection after installation. This screw is suited for mechanical assembly, equipment fabrication, and maintenance tasks across HVAC, plumbing, electrical, and general trade applications.

This fastener is appropriate for residential and light commercial assemblies where a metric M5 thread pitch of 0.80 is specified. The button head profile keeps a low vertical footprint when clearance is limited. The 3mm hex socket drive is compatible with standard metric hex keys and socket drivers. A thread fit class of 4G and 6G ensures consistent engagement with mating threads. Sold in a package quantity of 25, this screw is well suited for service technicians and fabricators who need a reliable supply of metric fasteners on hand.

Key Features

• M5x0.80 metric thread with 35mm length under head — partially threaded
• Button head, low-profile design for clearance-restricted assemblies
• 3mm hex socket drive compatible with standard metric allen keys and drivers

• Bright, uncoated finish for dimensional consistency
• Meets ISO 7380 fastener standard with thread fit class 4G and 6G

Compatibility

Designed for use in metric M5x0.80 threaded assemblies conforming to ISO 7380. Thread fit classes 4G and 6G are compatible with standard metric mating hardware within those tolerance ranges.

Installation Notes

Installation requires a 3mm hex socket driver or allen key. Ensure mating threads are clean and free of debris before driving to avoid cross-threading or galling, which is more common with stainless fasteners. Apply an appropriate anti-seize compound if the assembly will be subject to repeated removal or high-moisture exposure. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
