Gangtong Zheli is China manufacturer & supplier who mainly produces DIN 186 Grade 8.8 High Quality White Zinc Plated T Head Bolts with many years of experience. Hope to build business relationship with you. Specially engineered flange bolts feature anti-rotational "teeth" designed to securely grip and embed into the material being fastened. These teeth operate in a manner akin to the locking rings on a soda bottle or milk jug, but they generally require more force to turn backward. This unique design sets flange bolts apart, making them a strategically distinct choice compared to standard bolts.

A crucial companion to the flange bolt is the flange nut. While it bears similarities to a regular nut, one side of the flange nut is broader than the other, ensuring an even distribution of pressure. The synergy between the flange nut and flange bolt is particularly effective, and, in some instances, may eliminate the need to purchase separate washers, potentially reducing costs. Applying the proper torque to the flange bolt-nut assembly ensures that the fasteners remain securely in place, and they can only be loosened by an external force, such as a mechanic, preventing self-loosening.

M12 Grade 8.8 High Tensile White Zinc Plated Square Head Bolts

T head bolt differs from the common bolt in that it has a wider surface area under the head to provide for an even distribution of clamping pressure. This wider surface acts like a washer, eliminating the need to combine one with this kind of bolt. Square bolts are available in numerous sizes, strengths, and configurations. Like most other types of fasteners on the market, metric flange bolts are available for any applications that require them.
