Metallics BLS3410G – Frequently Asked Questions
1) What size lag bolt is the Metallics BLS3410G, and how many come in a box?
BLS3410G is a 3/4 inch diameter by 10 inch long hex head lag bolt, sold 25 to a box. Measured shank diameter runs 0.729 to 0.768 inch, and the length is 10 inches. If you need a different diameter, length, or pack count, other sizes and quantities in the BLS and JBLS series are available by request.
2) Can I use this lag bolt outdoors or in a damp, corrosive location?
Yes. The BLS3410G is galvanized steel and is intended for corrosive environments, so exterior framing, damp mechanical rooms, and coastal or wash-down areas are what it's built for. For bolts going into pressure-treated lumber or anywhere with standing moisture, galvanized is the finish you want rather than plain zinc.
3) Will this lag bolt meet a Buy American or ARRA requirement on a federal job?
The BLS3410G is flagged compliant for both Buy American and ARRA, which is what most federally funded work and many municipal specs call for. Country of origin is listed as multiple, so if your spec requires a single named origin on the certification, that is the detail to pin down with your submittal.
4) Do I need to drill a pilot hole for this lag bolt, or will it self-start?
It has a gimlet point so it will start on its own, but at 3/4 inch diameter you should still pilot it. A full-bodied lag of this size wedges hard in wood and can split the member or snap the head without a lead hole sized to the shank root. The spaced lag threads do the holding once it's in.
5) What standard and material grade does this hex lag bolt conform to?
Dimensions follow ASME B18.2.1-1996 and the steel is AISI 1006 to 1022, with a minimum tensile strength of 60,000 psi and hardness of Rockwell B70 to B100. That is the standard low-carbon lag screw spec, and it is the data to put on a submittal when the drawing calls out a dimensional standard for lag bolts.
6) Does the lag bolt come with washers, or do I order those separately?
Washers are not included, the box contains 25 bolts only. Under a 3/4 inch lag with a 1-1/8 inch hex head you'll want a structural or cut washer to spread the load into the wood, ordered as a separate line item.
7) Is a lag bolt the right fastener for anchoring into concrete or masonry?
No. A hex lag bolt with spaced threads and a gimlet point cuts its own thread in wood, it is not a concrete anchor. For concrete or block you need a wedge anchor, sleeve anchor, or a screw anchor rated for masonry. Use the BLS3410G for wood-to-wood or steel-to-wood connections where you are threading into solid timber.
8) Is there a minimum order on the Metallics BLS3410G lag bolts?
They ship as a boxed count of 25, and 25 is the order minimum. A full box runs 28.9 lbs, worth knowing if you are ordering several for a job site delivery or carrying them up to a roof.
