Shorty's Silverado's come with 2 silver and 6 black bolts to help distiguish the nose from the tail of your board.  They  are half threaded for strength against bending and breakage.  Manufactured to precise lengths for all applications, leaving no excess bolt sticking out past the nut.  Smaller counter-sinking head is lighter and puts a much smaller dent in your deck when installed, which helps prevent breakage.

Each pack contains 8 Phillips head bolts, 8 low profile nuts and a free sticker.

1.25" length, Philips screw head, pack of 8

These bolts can be used alone but ideally should be chosen if you're using 1/4" risers with your board setup, hence being 1/4" longer than your average skate hardware.
