YakAttack 1/4-20 Thread Knobs, 6 Pack, Item #CK1420-6
Convertible knobs with 1/4-20 Threads. 6 Pack
In standard YakAttack fashion, this knob does more than meets the eye. Purchased as a 1/4-20 female knob, it can be quickly converted to a 1/4-20 male knob by simply installing a socket head cap screw through it.
