Description
Overview
ISO 7380 defines a hexagon socket button head screw with a low rounded head. The button head provides a neat appearance and a broad bearing surface, while the internal hex drive allows installation where external spanner clearance is not available.
This selected size is specified with diameter M2.5, length 8 mm, thread M2.5, pitch 0.45 mm.
Sold in multiples of '200 pieces. 1 Box = '200 pieces.
Material, Grade & Strength
A2 stainless steel, commonly associated with 304 stainless, provides good general corrosion resistance for outdoor, clean industrial and food-related environments. Stainless threads can gall, so suitable anti-seize may be required.
Finish & Corrosion Protection
Corrosion resistance is provided by the stainless material itself rather than a plated coating.
Typical Uses
ISO 7380 button head screws are used on visible assemblies, equipment covers, guards, frames, furniture, panels and light machinery where a low-profile rounded head is preferred.
Technical Tips
- Use the correct hex key or socket bit to avoid rounding the drive.
- Button heads are lower than socket cap screws, so check suitability for high-load joints.
- Use washers where surface protection or load spreading is needed.
- Select stainless or coated finishes for exposed environments.
Frequently Asked Questions
When should a button head be used? Use it where appearance, low profile and internal hex drive access are more important than the higher head strength of a socket cap screw.
