The "Sankquick Nut" is a nut that can be tightened with a single touch. It features easy operation by simply pushing it in, making it excellent for work efficiency, especially in areas where tightening is difficult, and it excels in temporary fastening. The inside of the quick case (equivalent to a regular nut) has a tapered structure, and it is divided into three wedge-shaped screw sections (equivalent to the threads of a regular nut) that are fitted inside. 【Features】 ■ Can be inserted straight without rotation up to the tightening point, tightening is possible with one and a half turns ■ Maximum tightening torque, with a 95% engagement rate of the bolt's threaded section, designed not to loosen ■ Can be tightened even if the bolt threads are damaged ■ Good workability in difficult-to-tighten locations *For more details, please refer to the PDF document or feel free to contact us.

The "All Quick Nutter" features a tapered structure on the inside of the quick case, with three wedge-shaped screw threads embedded inside. It can be secured by turning it 1 to 1.5 rotations from the point where the bolt's threads engage until tight. When removing, simply loosen it by three rotations and align the indicator to OFF for quick removal. Additionally, it was previously impossible to work with damaged threads, stripped peaks, rust, or differences in thread pitch on bolts and nets, but with this product, tightening can be done easily even in such cases. 【Features】 ■ A nutter renowned for its ideal structure ■ Straight insertion to the tightening point without rotation ■ Tightening is possible with 1.5 rotations, and removal can be done with 3 rotations ■ Removal is also quick and without rotation *For more details, please refer to the PDF document or feel free to contact us.

The "SSN (Super Slit Nut)" is a screw that can withstand 1 million vibration tests (NAS test) and exhibits excellent anti-loosening effects. It is equipped with a spring function that generates pre-bolting torque at the top of the nut. There are two springs at the top of the nut with a specific shape, and during tightening, these parts undergo elastic deformation, gripping the threads of the counterpart near the slit area with spring force. This simple structure provides stable anti-loosening effects. 【Features】 ■ Anti-loosening performance that withstands 1 million vibration tests (NAS test) ■ Reusable ■ Prevents dislodgment in environments with intermediate stops or unstable axial forces ■ Can be produced in small lots with short delivery times ■ Adjustable strength of anti-loosening (pre-bolting torque) *For more details, please download the PDF or contact us.
