Simple hardware like the right-sized knobs can be difficult to find when you need them, and you can pay a whole lot more that you’d think proper once you do.  Snap-Lock knobs are a cheap and versatile solution.  They allow you to assemble your own custom knobs using the nut or bolt of your choice so you don’t have to keep a dozen different sizes on hand.

The manufacturer molds the knobs with a hex hole that accepts standard hex nuts or bolts.  Just push the appropriate fastener into the Snap-Lock knob and it’ll lock into position securely.

The Snap-Lock knobs are available in star knob, T-knob, and 3-prong knob styles.  Star knobs fit 1/4″, 5/16″, and 3/8″ imperial thread sizes or M6, M8, and M10 metric thread sizes, while T-knobs and 3-prong knobs fit only a smaller subset of those sizes.  Pricing starts at about a buck a knob or around $8 for a ten-pack.

    Custom and home made jigs are the best. You can make them fit you exact machine and your exact purpose. Also you can take it a part if it is a one time thing.

    I need snap lock knobs to fit a 1/2″ bolt (3/4″ hex head).

    I need ball knobs made like this. 1″ round. No one makes these and ball knobs this size are like a buck each, are you kidding me? this is why I’m building a small injection mold machine. Oh, and these snap lock or similar knobs in my local hardware store are like 2.99 each, are you kidding me? Thieves!
