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.

Specially designed flange bolts are equipped with anti-rotational “teeth” designed to “bite” or dig into the material one might need to fasten together. Similar to the locking rings one might see on a soda bottle or milk jug, these teeth on the flange bolt can be turned backward, but often require more force. This type of design is what makes a flange bolt uniquely and strategically different from a common bolt.
An essential addition to the flange bolt is the nut. While it is similar to an ordinary nut, one side of the nut is wider than the other to ensure even pressure distribution. The flange nut and flange bolt work well together, and in some cases may reduce costs by eliminating the need for purchasing separate washers. Proper torque on a flange bolt-nut combination will ensure that the fasteners never become loose by themselves. Only an outside force, such as a mechanic, can loosen these types of flange bolts.
