What is Grade 8.8 Bolts ?

Grade 8.8 bolts are highly used and the most demanded bolts that are being used in industries today. These bolts are made from superior raw materials and extraordinary equipment. These bolts are considered the most durable and ductile grades. These Grade 8.8 bolts are finely specified and made from extreme quality material. The elasticity and malleability of the grade are also very high.

Grade 8.8 is normally available in various finishing such as carbon finishing, zinc coating, and hot-dip galvanized. These types of grade 8.8 bolts are commonly used for various industrial as well as commercial purposes. These bolts are generally used for high-temperature applications. These bolts are commonly used for joining two or more objects together.
