Metallics BLS17 – Frequently Asked Questions
1) Is a 3/4 x 5 zinc plated lag bolt OK for outdoor or damp locations?
Zinc plating on the BLS17 gives light corrosion protection, which covers covered exterior and general damp indoor work. For direct weather exposure, coastal air, or contact with treated lumber, a hot dip galvanized or stainless lag is the better choice because zinc plating is a thin sacrificial coating.
2) Do I need to pre-drill for a 3/4 inch lag bolt?
Yes. At 3/4 inch diameter a lag screw must have a pilot hole, or you'll split the wood or snap the head off driving it. Standard practice is a clearance hole through the member being fastened and a smaller pilot in the receiving member sized to the shank less the thread. The BLS17 is a hex head, so it drives with a socket or impact wrench, not a screwdriver.
3) Does the Metallics BLS17 lag bolt come with washers or anchors?
No. The BLS17 is supplied as the lag bolt only, 25 pieces. Flat washers under the hex heads, and shields or expansion anchors if you're going into masonry rather than wood, have to be ordered separately.
4) Can I use a lag bolt like this to anchor into concrete or block?
Not on its own. A lag screw cuts its own thread in wood; in concrete or block it needs a lead or plastic shield to bite against, or you switch to a proper concrete anchor such as a wedge anchor or a large diameter screw anchor. The BLS17 3/4 x 5 lag is intended for wood and lag-shield applications.
5) What part number do I order for the Metallics 3/4 x 5 hex lag bolt?
Order Metallics BLS17. That's the manufacturer part number for the 3/4 x 5 zinc plated steel hex head lag bolt, packed 25 per box, and it's the only configuration under that number.
