Metallics M50338 – Frequently Asked Questions
1) What does the .145 shank diameter on a threaded stud mean for the powder actuated tool I am using?
The .145 inch shank is the drive pin portion that gets fired into concrete or steel, and it is the standard shank diameter for .27 caliber powder actuated and gas tools that take .145 pins. The M50338 drives the 1-1/4 inch shank into the base material and leaves the 1/4-20 threads exposed for hanging. Confirm your tool is set up for .145 shank pins before loading.
2) Is the M50338 a bolt I can put in a drilled anchor, or is it a drive pin?
It is a drive pin style stud, not a machine bolt. The 1-1/4 inch, .145 diameter shank is unthreaded and meant to be driven into concrete or structural steel by a powder actuated tool, with only the 1/4-20 portion left standing proud for a nut. If you want a fastener that goes into a drilled hole, you need a threaded rod with a drop in anchor or a wedge anchor instead.
3) Can I use the Metallics M50338 threaded stud to hang electrical conduit or fixtures from a concrete ceiling?
That is the job it is built for. The M50338 is a drive pin with 1/4-20 threads on the exposed end, so once the 1-1/4 inch shank is set in the deck you thread on a nut, a hanger, a beam clamp with a 1/4-20 tap, or a conduit clip. It is an electrical construction hardware stud, commonly used for conduit hangers, box supports, and lighting drops.
4) How much thread length do I get above the surface with the Metallics M50338?
The threaded portion is 1/4-20 x 1-1/4 inch, separate from the 1-1/4 inch shank that goes into the base material. So after the pin is driven flush you have up to 1-1/4 inches of 1/4-20 thread standing out, enough for a hanger plus a nut and washer. If your assembly stack is deeper than that, step up to a longer threaded stud.
5) What part number do I order for the Metallics 1/4-20 threaded stud with the .145 shank?
Order Metallics M50338. That is the manufacturer part number for the 1/4-20 x 1-1/4 threaded stud with the 1-1/4 inch, .145 diameter shank, and it is the only configuration under that number.
