Calibre Door Closers SNB-175-AL – Frequently Asked Questions
1) What thread size are the Calibre SNB-175 sex bolts, and will they take a standard 1/4-20 machine screw?
The SNB-175 sex nut and bolt set is 1/4"-20, so it mates with standard 1/4-20 coarse machine thread. That is the thread most commercial door closers, exit devices, and pull hardware use for through-bolting, so if the hardware you are mounting is drilled for 1/4-20 fasteners, this set threads straight in.
2) What does a sex nut and bolt actually do on a door, and do I need one instead of wood or machine screws?
A sex nut and bolt is a two-piece through-bolt: the barrel (the nut half) passes through the door from one face, and the bolt threads into it from the other, clamping the door between the two heads. You use it when the door skin cannot hold a screw on its own, hollow metal, aluminum, or a mineral-core wood door, and when the hardware has to resist being pulled off the face. The Calibre SNB-175 is a commercial-duty set in 1/4"-20.
3) What finishes do the Calibre SNB-175 sex nuts and bolts come in?
Two: AL aluminum and DU storefront bronze. Those are the two finishes that let the fastener heads disappear against typical storefront and commercial aluminum entrances, clear anodized frames take the aluminum, dark bronze anodized frames take the storefront bronze. Pick the one that matches the closer or panic hardware you are bolting through, since the bolt head sits exposed on the pull side of the door.
4) Can I use the Calibre SNB-175 sex bolts to mount a door closer on an aluminum storefront door?
That is what the set is built for. The SNB-175 is a commercial 1/4"-20 through-bolt from Calibre Door Closers, and it comes in aluminum and storefront bronze, the two finishes that match storefront entrances. Through-bolting is the normal way to hang a closer on a thin aluminum stile, since the stile wall is too light to hold a tapped screw under closer load. Match the barrel length to your door thickness when you order.
