It prevents voids from occurring on the back side and ensures good adhesion along the entire length of the bolt.
The "SN Twist Bolt" is a twisted rebar lock bolt that has been cold twisted from specially manufactured high-strength deformed steel bars to further enhance its strength. When this product is inserted into a borehole filled with mortar, the spiral ribs and lateral bumps rotate the mortar, improving insertability. As a result, it prevents the formation of voids behind the ribs and bumps, ensuring good adhesion along the entire length of the bolt. 【Features】 ■ Forms a surface shape that is easy to insert into boreholes filled with mortar ■ Effective in preventing the formation of voids between the mortar and the bolt ■ Adhesion performance with mortar is superior to that of deformed steel bars ■ Rolled threads based on JIS-B-0205 standard metric coarse threads *For more details, please refer to the PDF document or feel free to contact us.
