Product Description

Double Sided Head Hanger Screw

Double Sided Head Hanger Screw are studs used to suspend objects from or attach items to wood. Like a typical stud, they are headless, double-ended bolts that have threads at each end-lag threads to screw into wood but, at the other end, machine screw threads to accept a nut or thread into an internally threaded (tapped) hole. Coupling nuts and threaded rod are often used with hanger bolts to suspend electrical conduits, junction/pull boxes, fixtures and sheet metal. The furniture industry uses them with corner brackets, clinch nut plates, tee nuts and whenever wood and machine screw threads are needed in a single fastener. Double Sided Head Hanger Screw are also known as: couch bolts, headless hanger bolts, hanger screws.Being headless, a little ingenuity is needed to drive them into wood-see below for a few installation tips.

Threads are standard right-hand at both ends. The machine screw threads are Unified inch coarse series (UNC, Unified National Coarse) and the lag threaded portion has coarse, widely spaced threads that end in a tapered blunt point designed to start threading into a properly sized pilot hole. Plain center style has an unthreaded body section; fully threaded types, also called closed center, do not have an unthreaded section.

Common sizes are 8-32, 10-24, 1/4-20, 5/16-18 and 3/8-16 and lengths range from 3/4"to 6". The number of threads per inch (32, 24, 20, etc.) refers to the machine screw threaded end. Measure length from end to end.
