Bolt Knob (Intermediate) - carbon fiber

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 extremes.

You will not find a stronger and lighter bolt knob anywhere!
