Special shapes are applied to the 'incomplete screw section' to improve work efficiency! This is an original product with a patent. Problems with conventional products due to incomplete screw sections: - They tend to float from the mounting surface. - Chamfering and deburring on the counterpart are required. - Reduced contact area of the screw leads to weaker torque. Improvements made to the screw base: - No incomplete screw section. - It adheres closely to the mounting surface, preventing floating. - No need for deburring on the counterpart & absorbs burrs. - Reduces the number of processes and costs for chamfering on the counterpart. - Increased contact area of the screw results in stronger torque. ● Material, Treatment, and Sizes: Stainless Steel 303 (degreased): BSU-D M2/M2.5/M2.6/M3/M4 Brass (nickel-plated): BSB-DE M2/M2.5/M2.6/M3/M4 ★ For more details, please download and check! ★ We offer free shipping for booklet versions; you can request as many as you need here: https://hirosugi.co.jp/form_hirosugi/index.php
