Turn wrenches, turn heads. Color Lab brings race grade titanium hardware in bold, lab tuned anodized hues: ultra light, ultra strong, unmistakably yours. This is the 1/4-20 x 3/4 socket head lock collar bolt, the size used in other manufacturers' rear brake hubs on outlaw karts and junior sprints.

Every bolt is machined from lightweight grade 5 titanium, so you take real rotating and unsprung weight out of the rear end without giving up the strength a brake hub clamp needs. Titanium also handles the heat that lives around a rear brake and will not corrode into the collar over a season.

The heads are drilled for safety wire, so once the bolt is torqued you can wire it and stop worrying about it backing out mid main.

Material: grade 5 titanium
Thread: 1/4-20
Length: 3/4 in
Head: socket head, drilled for safety wire
Finish: anodized, eight Color Lab colors
Weight: 3.8 g, plus or minus 0.5 g

Please note this is not the bolt used in our own brake hub; it is sized for other companies' rear brake hubs. Price is per bolt, so order the quantity your hub takes.

Colors, left to right in the first image: Go for Gold, Victory Violate, Royal Blue, Five Three Blue, Chartreuse, Pink Lemonade, Pearl, Oil Slick. 5/16-18 bolts are shown in the photos.

Actual colors may vary slightly. Victory Violate and Royal Blue are close, though in person there is a slight shade difference in direct light. Pink Lemonade appears pink with light touches of yellow on the edges of the threads. The finish on both Pink Lemonade and Pearl may come out matte. Over time the anodizing may wear off the threads or off the head from wrench contact, so take care while installing to get the longest color life.

All colored hardware is made to order. Please allow 1-2 business days for processing.
