Minerallac 600 – Frequently Asked Questions

1) What threaded rod does the Minerallac steel set screw beam clamp take?
The tapped holes are 1/4"-20, so it accepts 1/4" threaded rod. There are two of them, one on the bottom and one on the back, so you can hang straight down off the flange or run the rod out horizontally from the back of the clamp. The supplied set screw is also 1/4"-20 x 1".
2) Which size do I order and what are the part numbers?
Three sizes are offered: 1/4" is part number 600, 3/8" is 602, and 3/4" is 602B. Order by the size that matches the structural member and the hanging hardware you are using.
3) I need a malleable iron beam clamp instead of steel - what should I use?
Two malleable iron options sit alongside the zinc plated steel Minerallac 600 series clamp: the Appleton IS-500, a screw-type clamp with a hexagonal head and 1/4-20 tapped hole, and the Thomas & Betts RC-2SC Steel City clamp, a 2-inch galvanized malleable iron beam clamp. The RC-2SC is the one to look at if you need a wider jaw than the Minerallac's 1/2" flange capacity.
4) Will the Thomas & Betts RC-2SC work where I would otherwise use a Minerallac 600 clamp?
Not interchangeably in every case. The RC-2SC is a 2-inch galvanized malleable iron beam clamp, so it is sized for a wider beam flange than the Minerallac 600 series, which is built around a 1/2" flange capacity and a matching maximum jaw opening. On a thin flange the Minerallac clamp is the closer fit; on a heavier structural flange the RC-2SC is the one that will seat.
5) How tight do I torque the set screw on this beam clamp?
The clamp carries a 40 torque rating, and the screw itself is case hardened steel with an angled tap so it bites into the beam face as it draws up. Run it to that figure with a torque wrench or screwdriver adapter rather than guessing; overdriving a 1/4"-20 hardened screw into a hardened flange is how you gall the threads.
6) Is a zinc plated beam clamp OK outdoors or in a wet area?
The finish here is zinc plated steel, which the product data describes for indoor electrical environments. It is fine for warehouses, plant interiors, ceiling spaces and plenums. For exterior work, washdown areas or a corrosive process environment, step up to a galvanized malleable iron clamp such as the Thomas & Betts Steel City RC-2SC.
7) What is the difference between a stamped steel beam clamp and a malleable iron one?
This Minerallac clamp is formed steel at 0.089 gauge with a hardened set screw, compact at 1.40" x 0.87" x 1.68", and suited to light conduit and bridle ring support. Malleable iron screw-type clamps like the Appleton IS-500 hexagonal head clamp or the Steel City RC-2SC are heavier castings for bigger flanges and heavier loads. If you are standardizing on 1/4"-20 rod across a job, the Kindorf FBC1 structural beam clamp is another 1/4"-20 option and comes in packs of 100.
8) Do I need to drill or weld the beam to use this clamp?
No drilling and no welding. The clamp hooks over the beam flange and the set screw locks it in place, which is what keeps it acceptable on structural steel where field drilling is not allowed. That also makes it removable and repositionable if the conduit route changes.
9) Which beam clamp accepts Minerallac conduit hangers and bridal rings directly?
The Minerallac 600 series clamp is the one specified for that combination - its 1/4"-20 tapped holes on the bottom and back accept threaded rod, Minerallac conduit hangers #0 through #5, and bridal rings. The Appleton IS-500 and Kindorf FBC1 are also tapped 1/4-20, so they take 1/4"-20 rod, but the hanger pairing is called out for the Minerallac clamp.
10) Which beam clamp should I buy if I am ordering in bulk for a large conduit job?
The Kindorf FBC1 structural beam clamp for 1/4"-20 threaded rod is sold in packs of 100, which suits standardizing across a large run. It takes the same 1/4"-20 threaded rod as the Minerallac 600 series, so rod and hardware carry over between the two.
11) I need a US-made beam clamp for a government job - which one qualifies?
The Minerallac 600 series beam clamp is manufactured in the United States, which is the deciding factor on domestic-content jobs. Among the alternatives, the Appleton IS-500 and the Thomas & Betts RC-2SC Steel City clamp are the malleable iron counterparts and the Kindorf FBC1 is the bulk-pack option, but the domestic origin is the Minerallac clamp's claim.
12) Is the Minerallac beam clamp made in the USA for projects with domestic sourcing requirements?
Yes, country of origin is the United States, which matters on public and institutional work carrying domestic content language in the specification.
