Metallics BLS8SS – Frequently Asked Questions
1) Will stainless lag bolts hold up outdoors or in a wet mechanical room?
Yes. The BLS8SS is 18-8 stainless steel, which gives better corrosion resistance than galvanized steel lag bolts. That makes it the right choice for exterior strut and conduit mounting, rooftop equipment supports, and damp plant rooms where zinc plating eventually sheds and the head rusts out.
2) Is this lag bolt strong enough for hanging pipe and conduit supports?
Grade 2 with an approximate minimum tensile strength of 100,000 to 125,000 psi and a hardness of Rockwell B95 to C32. That covers the usual electrical, plumbing, and HVAC hanging work it is intended for. For structural connections governed by an engineer's drawing, check the specified bolt grade before substituting.
3) What size pilot hole should I drill for a 1/4 inch x 5 inch stainless lag bolt?
The Metallics BLS8SS lag bolt has a measured shank outside diameter of 0.237 to 0.260 inches with 10 threads per inch, so your pilot hole needs to clear the shank but still let the spaced threads bite. In solid softwood that means drilling at roughly the shank's root diameter, not the full 1/4 inch over the thread depth. The gimlet point starts the hole, but at 5 inches of length a pilot is still needed to avoid splitting the member.
4) Does the Metallics BLS8SS meet Buy American requirements for a federal job?
The BLS8SS is flagged compliant for both ARRA and Buy American, which is what a government or institutional procurement file usually needs on the fastener line. Country of origin is listed as multiple, so if your contract requires a single named origin, confirm the origin on the lot you receive.
5) How many lag bolts come in a box, and can I buy fewer than a full box?
The BLS8SS ships as a box of 100 and the order minimum is 100 count, so a full box is the smallest purchase. Metallics does offer other sizes and quantities in the BLS and JBLS series by request if 1/4 x 5 inch or a 100-piece box is not what the job needs.
6) Is this a full-bodied lag bolt or a reduced-shank screw?
Full-bodied, with a hex head, spaced threads, and a gimlet point. The shank measures 0.237 to 0.260 inches, so it is close to the 1/4 inch nominal all the way to the head rather than necked down. That matters when you are pulling a bracket tight against wood and relying on the unthreaded shank for shear.
7) How much does a box of 100 stainless 1/4 x 5 lag bolts weigh for shipping or carrying up to a roof?
A box of the BLS8SS runs 5.89 lbs. Easy enough to carry on a lift or a ladder, and worth knowing if you are staging several boxes for a long run of rooftop supports.
