• A307 GRADE A SQUARE HEAD BOLT, PLAIN (INCH)
Square bolts (also known as square head bolts or square head machine bolts) offer less danger of wrench slippage in hand wrenching, as well as a greater bearing area. In addition, the square head style is more secure than a hex bolt style when fixed into a cored recess.
