Self-tapping screws that can be screwed in with low torque! The screwing torque is low, reducing fatigue during continuous screw tightening work!
Sanrock is an ideal tapping screw that forms strong internal threads with a small screwing torque. The cross-section of the screw part is shaped like a rice ball, with its apex offset in a spiral manner. These two structural features enable a small screwing torque and smooth screwing performance. Additionally, since the internal threads are formed through plastic processing, it generates little cutting chips, allowing for smooth fastening. ● For other functions and details, please download the catalog.

basic information
**Features** - The threaded part has a "spiral" rice ball shape. - The female thread is formed by plastic processing. - The shape below the thread of the Sunlock is "round wire." **Comparison with Conventional Tapping Screws** - The screw-in torque is low, which reduces fatigue during continuous work. - Compared to the screw-in torque, the holding power is high, as the female thread is raised through plastic processing, resulting in strong holding power. - There is a high resistance to vibration. - For other functions and details, please download the catalog.

Company information
In 1927, our company started as a manufacturing and sales business focused on hardware products such as cotter pins, and in 1957, we began mass production as a pioneer of stainless steel screws. The frontier spirit that lives on at Maruemu Seisakusho has led to the creation of core technologies based on the accumulation of history and skills, including "product development of new materials, material processing, and fastening technology."
