Low-torque tapping screws that can be screwed in! With low screwing torque, it reduces 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 chip waste and allows 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 internal thread is formed through plastic processing. ● The shape below the thread of the Sunlock is "round wire." 【Comparison with Conventional Tapping Screws】 ● The screwing torque is low, which reduces fatigue during continuous work. ● Compared to the screwing torque, the holding power is high, as the internal thread is raised through plastic processing, resulting in high holding power. ● It has 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 our history and the accumulation of skills, including "product development of new materials, material processing, and fastening technology."
