Minerallac 74624J – Frequently Asked Questions
1) Will a 1/2-13 hex cap screw thread into a 1/2 inch coarse nut or tapped hole?
Yes. The Minerallac 74624J is a 1/2-13 screw, meaning a 1/2 inch nominal diameter with 13 threads per inch, which is the standard UNC coarse pitch for 1/2 inch fasteners. It mates with any 1/2-13 nut, coarse-tapped strut channel nut, or 1/2 inch coarse tapped hole. It will not engage a 1/2-20 fine thread.
2) How thick a material can I clamp with a 1-1/2 inch hex cap screw?
Overall screw length is 1-1/2 inches measured under the head, and the 74624J is threaded the full length. In practice that means your stacked material plus washers plus nut has to fit inside 1-1/2 inches. For a nut on the back side, figure roughly 1/2 inch consumed by a 1/2 inch heavy hex nut and washer, leaving about an inch of material. Into a tapped hole or channel nut, the full 1-1/2 inches is available for engagement.
3) Is an 18-8 stainless hex cap screw suitable for outdoor or wet locations?
18-8 stainless steel (the 300-series austenitic grade used in the Minerallac 74624J) resists corrosion without plating, so it holds up outdoors, in damp mechanical rooms, and in coastal exposure better than zinc-plated carbon steel. Minerallac lists marine and outdoor installations among its applications. For constant salt spray immersion, 316 stainless is the harder-duty choice.
4) What is the difference between a full thread and a partially threaded hex cap screw, and does it matter here?
Full thread, which is how the 74624J is made, runs threads all the way from the point to the head. That lets you use any grip length up to 1-1/2 inches and get maximum thread engagement into a nut or tapped hole. A partially threaded bolt puts an unthreaded shoulder in the joint, which is preferred where the bolt body carries shear across a bolted steel connection. For strut, equipment mounting, and general anchoring, full thread is the easier part to work with.
5) Do nuts and washers come with the Minerallac 74624J hex cap screw?
No. The 74624J is supplied as hex head cap screws only, so order 1/2-13 coarse nuts and 1/2 inch flat or lock washers separately if the connection needs them. Match them in 18-8 stainless to keep the joint consistent with the screw.
6) Is this a hex cap screw or a lag bolt? Will it bite into wood?
It is a machine-threaded hex cap screw, not a lag. The 1/2-13 coarse thread is cut to mate with a nut or a tapped hole and will not form its own thread in wood or concrete. For wood framing use a lag screw; for a cap screw like the 74624J you need a through bolt with a nut, a tapped hole, or an insert.
7) Can I mix stainless hex cap screws with galvanized channel and fittings?
You can, but keep dissimilar-metal contact in mind. The 74624J is uncoated 18-8 stainless with a bare silver finish; bolting it to galvanized strut in a wet location lets the zinc coating sacrifice at the contact point over time. Indoors and in dry runs it is a non-issue, and matching the nut and washer to the same 18-8 stainless is the usual practice.
8) What tool do I drive a 1/2-13 hex head cap screw with?
A hex head takes a standard open-end, box, or socket wrench, or an impact socket. The six-sided head on the 74624J is made for high torque, so a socket on a ratchet or impact gun is the normal choice when you are running a quantity of them. Hold the nut with a second wrench on through-bolted connections.
