Solution to the mounting problem on thin plates with incomplete screw section non-stainless spacer.
A spacer with a special shape is applied to the "incomplete screw section" male thread. It can absorb the burrs of the mounting counterpart and allows for direct installation flat to the base.
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
