3/8" unf x 1" Flange Head Bolt.
	
Just right for mounting your front caliper to the mounting bracket.
	
Designed with a larger flange than normal to ensure good clamping loadto reduce caliper flex.
	
Also has a 9/16" hex which is perfect when used with our other 9/16" hex head bolts so you only need 1 size spanner when doing a quick front change!
