Twisted Bar Steel Lock Bolt "SN Twist Bolt"
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.
