It prevents the occurrence of voids on the back side and achieves 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-tensile deformed steel to further enhance its strength. When this product is inserted into a borehole filled with mortar, the spiral ribs and cross ribs rotate the mortar, improving the ease of insertion. As a result, it prevents voids from forming behind the ribs and joints, 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 ■ Effectively prevents the formation of voids between the mortar and the bolt ■ Adhesion performance with mortar is superior to that of deformed steel ■ Rolled threads based on JIS-B-0205 standard metric coarse threads *For more details, please refer to the PDF materials or feel free to contact us.
