Our take on the 12-24 x 1 1/4 Machine Screws, Unslotted Hex Head, Steel, Zinc

A 12-24 machine screw with a 1 1/4-inch length, an unslotted hex head and a zinc-plated steel finish. The unslotted head is driven with a wrench or socket rather than a screwdriver, which suits tamper-resistant or high-torque assemblies. Zinc plating gives basic indoor corrosion protection. The listing is sold as a bulk carton weighing about 25.6 lbs, so it is aimed at shops and contractors rather than a single repair.

Questions and answers

What does 12-24 mean on this screw?
It is a #12 diameter with 24 threads per inch, a standard US machine thread. It threads into matching 12-24 nuts or tapped holes.
Why is the head unslotted?
There is no slot for a screwdriver. You turn it with a socket or wrench, which gives more torque and makes it harder for someone to remove by hand.
Can I use these outdoors?
Zinc plating is for indoor use. For outdoor or wet conditions, choose stainless steel or a heavier hot-dip galvanized finish.
How many screws are in the carton?
The listing gives only the carton weight, about 25.6 lbs, not a piece count. Ask the seller for the exact quantity before ordering.
What length is 1 1/4?
The screw is 1 1/4 inches long. For machine screws this is normally measured under the head, so check your grip length against that.
