PDQ 63905308 – Frequently Asked Questions

1) What is the PDQ 639053-08 sex bolt pack used for?
PDQ 639053-08 is a four-pack of sex bolts (sex nut and bolt fasteners, SNB) for PDQ exit devices. Sex bolts are through-bolt fasteners used to mount a device or trim so the two halves thread into each other through the door, rather than relying on wood or sheet-metal screws into the door face. It is a genuine PDQ fastener part, finish 605/606.
2) How many sex bolts come in the PDQ 639053-08 pack?
Four. The 639053-08 is sold as a 4 pack, which is the quantity a typical exit device or outside trim mounting uses. If you are through-bolting several openings in a building, order one pack per device.
3) Do I need sex bolts instead of wood screws to mount an exit device?
For a commercial opening, yes in most cases. Sex bolts pass through the door and thread into each other, so the pull on the push bar is carried by the door rather than by screw threads in the face material. That matters on hollow metal and on any fire or panic rated opening. The PDQ 639053-08 is the genuine sex bolt pack for 6300 and 6400 Series devices, which are commercial rated hardware.
4) I'm servicing an installed PDQ exit device. Can I buy just the fasteners?
Yes. PDQ supplies the 6300 and 6400 Series as individual service parts, so you can order the 639053-08 sex bolt pack on its own without replacing the device. The same service range covers head chassis assemblies, latchbolts, rods and connectors, push bars, covers and end caps, strikes and shims, dogging and alarm conversion kits, screwpacks and signal switches.
5) What does the 605/606 marking mean on these PDQ sex bolts?
605/606 is the finish designation on the 639053-08 sex bolts, the bright and satin brass finish pair. On most installs the bolt heads sit behind the device or trim and are barely visible, but if your exit device hardware is brass toned, these match it.
