Bolt Knob - Intermediate
Genuine 3K Carbon Fiber
This is an intermediate-sized knob in between our tactical and 1" round options. The design starts at a 0.47" (12mm) stem diameter then has a concave taper to a 0.75" (19.05mm) diameter end with a 1.25" (31.75mm) overall length. This more difficult and expensive knob to mold is the result of
feedback from many customers over the years wanting a slightly smaller
knob but still gain extra leverage and clearance. The design includes a recessed end allowing for the bolt to be cycled
using just an index finger or thumb. A longer internal thread of 0.7" allow fitment to a wider range of factory handles as well as our M6 thread adapter. Threaded for the common
5/16" x 24 TPI manufactured from genuine 3K carbon fiber composite. This
is the same high-grade composite material used in expensive automotive
parts, aerospace components and racing bikes - it is never hot and
slippery, or cold and sticky like metal knobs can be in weather
You will not find a stronger and lighter bolt knob anywhere!
Proudly designed and manufactured in the USA - see our website www.BoltKnobs.com
