Knurled Hand-tight Long Step Screws

Our knurled hand-tight step screws are manufactured via integrated cold forging, delivering superior structural strength and stable dimensional precision. The outer circle of the head is equipped with dense knurling textures to boost friction, enabling quick assembly and disassembly by hand without auxiliary tools.

The extended long shaft design caters to deep installation demands of various tooling fixtures and testing equipment. We supply multiple surface treatment options, including galvanization for rust resistance and raw steel finish to cut costs. Customization services cover thread diameter, effective shaft length, flange thickness and head styles as per clients’ drawings or samples.

Each batch of finished fasteners undergoes strict dimensional testing and surface inspection to remove burrs and thread defects. They are widely adopted for repeated manual fastening scenarios, offering durable and reliable locking performance for long-term use.
