Short Description:

ISO 7380 Button Head Socket Screws

In equipment and enclosure assemblies where a low exposed profile, snag-free surface, and axial tool access matter, ISO 7380 button head socket screws have become the preferred choice for neat, space-saving fastening. Handan Haosheng Fastener Co., Ltd., a leading manufacturer based in Handan, China, specializes in producing high-quality ISO 7380 button head socket screws, offering a rounded head and internal hex drive that combine a clean appearance with reliable, flush installation.

At Handan Haosheng Fastener Co., Ltd., our ISO 7380 screws are engineered to match each assembly with the right size, material, and finish, helping equipment builders achieve a tidy exterior without raising head clearance.

Why Choose Haosheng ISO 7380 Button Head Screws?

Our button head screws deliver several key advantages:

• ✔ Two button head designs – ISO 7380-1 standard and ISO 7380-2 with a collar, both 2022 editions in metric M3-M16.
• ✔ Metric sizes M3-M16 – common sizes from M3 to M12 cover enclosures, panels, and brackets with flexible lengths.
• ✔ Reduced head loadability – head load is assumed at 80% of thread load; the property class is prefixed with a zero.
• ✔ Five surface finishes – black oxide, blue zinc, yellow zinc, zinc-nickel, and zinc flake, matched to environment and thread fit.
