Short Description:

DIN 916 (K) Knurled Cup Point Set Screws

In transmission and mechanical assemblies where precise shaft positioning, resistance to rotation, and a flush, headless profile are critical, DIN 916 (K) knurled cup point set screws (grub screws) have become the preferred choice for holding components on a shaft. Handan Haosheng Fastener Co., Ltd., a leading manufacturer based in Handan, China, specializes in producing high-quality DIN 916 (K) knurled cup point set screws, offering a headless body, internal hex drive and a serrated cup point that bites into the mating surface to improve positioning.

At Handan Haosheng Fastener Co., Ltd., our set screws are engineered to match each assembly with the right size, hardness class and knurl profile; we supply to the current ISO 4029:2026 / DIN EN ISO 4029:2026-06 route, covering the withdrawn DIN 916:1980-12 legacy designation with the edition and dimensions confirmed per drawing or sample.

Why Choose Haosheng DIN 916 (K) Set Screws?

Our knurled cup point set screws deliver several key advantages:

• ✔ Size range M1.6-M30 – steel M1.6-M30 and stainless M1.6-M24, product grade A, with M30 newly added for steel in the 2026 edition.
• ✔ Hardness class 45H – steel parts are specified by hardness class under ISO 898-5 (45H common), never by bolt tensile property classes.
• ✔ Knurled cup grip, zero tensile – serrated (K) teeth bite the shaft for rotation resistance; ISO 4029:2026 confirms set screws are not for tensile load.
• ✔ Five surface finishes – plain, black oxide, phosphate, zinc and zinc flake, with stainless parts cleaned and passivated.
