Super Spiral Bolt SP24

Super Spiral Bolt SP24

The head protection materials (cap/mat) for waterproof sheet installation are no longer necessary.

The "Super Spiral Bolt SP24" is a high-strength locking bolt that inherits the excellent features of the "SN Twist Bolt." It features a newly designed special rib and screw section that are simultaneously formed during the round steel rolling process, resulting in no cross-sectional defects in the screw section and consistent strength throughout its length. 【Excellent Characteristics】 - It uses high-strength material SD685, achieving a high yield load of over 297 kN while being even lighter (3.4 kg/m) than the SN Twist Bolt. - By maintaining the same material diameter and reproducing the surface shape of the SN Twist Bolt, the insertion resistance is equivalent to that of the SN Twist Bolt. - It inherits the excellent anchoring characteristics of the SN Twist Bolt, with high adhesion toughness against ground deformation during the early age of the anchoring material, making it less prone to adhesion failure. - The adoption of the special-shaped nut "S Nut" reduces the protrusion of the nut and bolt, eliminating the need for protective materials (caps/mats) during waterproof sheet installation. *For more details, please refer to the PDF document or feel free to contact us.*
