B-LINE SB1003AYZ – Frequently Asked Questions
1) What thread size is the B-Line J-bolt, and will a 5/16 inch nut fit it?
The B-Line SB1003AYZ J-bolt is threaded 5/16-18, so it takes standard 5/16-18 hardware: a 5/16-18 hex nut, and 5/16 flat and lock washers over the threaded leg. That is the same coarse thread used on most strut and channel hardware in the 5/16 size, so it mates with the nuts and washers already on the truck.
2) Is the yellow zinc finish on the B-Line J-bolt OK outdoors or in a damp mechanical room?
Yellow zinc chromate over steel is a plated indoor and protected finish. It handles the humidity of a mechanical room, a ceiling plenum, or an interior electrical room fine, but it is not a weathering finish. For a roof, an exterior wall, a parking structure, or a wash-down area, go with hot dip galvanized or stainless hardware instead, the plating on this one will bloom and rust once it sees standing water and UV.
3) Does the B-Line J-bolt come with a nut and washer, or do I have to order those separately?
The SB1003AYZ is sold as the bolt alone, one piece at .13 lb. Nuts, washers, and any channel nut or strut fitting are separate line items. If you are ordering these by the box for a hanger run, add matching 5/16-18 nuts and 5/16 washers in the same yellow zinc or better so you are not mixing finishes on the same connection.
4) What is a J-bolt used for in electrical work, and when should I use a different anchor?
A J-bolt is a hooked threaded rod: the curved end catches over an edge, rod, or through a drilled hole, and the threaded leg takes a nut to draw the connection tight. On electrical work it hangs or anchors conduit, strut, boxes, and light fixtures where there is an existing lip or member to hook. If there is nothing to hook over, a J-bolt is the wrong part, into concrete or masonry use a wedge or sleeve anchor, into a steel beam flange use a beam clamp, and through a solid panel use a through bolt.
5) Is B-Line SB1003AYZ the same as an Eaton part number, or do I need to order both?
Same part. B-Line is Eaton's support systems brand, so SB1003AYZ is the full manufacturer part number and there is no separate Eaton number to cross to. Order it as SB1003AYZ, yellow zinc, 5/16-18.
6) How much weight can the B-Line SB1003AYZ J-bolt hold?
Steel is the material and 5/16-18 the thread on the SB1003AYZ, but the load figure that matters on a hanger is the rated capacity of the whole assembly, the bolt, the nut, and whatever it hooks to, and it is governed by your local code and the engineer of record on the job. Size the support from the load table for the hanger system you are building rather than from the bolt alone, and keep the connection in single shear or straight tension, a J-bolt loaded by prying the hook open is well off its intended load path.
