Red Head WAG12414;R – Frequently Asked Questions
1) What drill bit size do I need for the Red Head Trubolt 1/2 inch galvanized wedge anchor?
Drill with a 1/2 inch carbide bit. The Trubolt wedge anchor is a nominal 1/2 inch diameter anchor in all three lengths (4-1/4, 5-1/2 and 7 inch), and the hole diameter matches the anchor diameter because the wedge clip expands against the hole wall as the nut is torqued. Minimum embedment is 2-1/4 inches, so the hole has to be drilled deeper than that plus whatever debris collects at the bottom.
2) Which length Trubolt anchor do I need for the thickness of material I'm bolting down?
Pick the length by the fixture thickness you have to clamp. The 1/2 x 4-1/4 handles up to 2 inches of fixture, the 1/2 x 5-1/2 up to 3-1/4 inches, and the 1/2 x 7 up to 4-3/4 inches. All three hold the same minimum 2-1/4 inch embedment in the concrete, so the extra length goes into the material above the slab, not into the hole.
3) How close to a slab edge can I set a 1/2 inch Trubolt wedge anchor, and how far apart?
Minimum edge distance is 3-15/16 inches and minimum anchor-to-anchor spacing is 7-7/8 inches for the 1/2 inch Trubolt. Expansion anchors push outward against the hole, so getting closer than that to a free edge risks spalling the concrete and losing the set. If your baseplate holes land tighter than 7-7/8 inches on center, you need a smaller diameter anchor or an adhesive anchor instead.
4) What size hole does my baseplate need for a 1/2 inch wedge anchor?
Two numbers, depending on how you install. If you spot the hole through the fixture and then lift the fixture off to drill, the fixture hole can be 1/2 inch. If you are drilling through the fixture and driving the anchor in place, the fixture hole needs to be at least 9/16 inch so the expansion clip passes through without snagging.
5) Can I set a Trubolt wedge anchor into hollow block or brick?
No. Wedge anchors like the Trubolt are rated for solid concrete as the base material; the wedge clip needs continuous material around the hole to expand against. In hollow CMU or brick the clip has nothing to bite and the anchor pulls out. For hollow block use a sleeve anchor, toggle, or screen tube with adhesive instead.
6) How much should I torque a Red Head Trubolt 1/2 inch wedge anchor, and what wrench fits the nut?
Maximum torque is 55 ft-lbs on all three 1/2 inch lengths, and the nut takes a 3/4 inch wrench or socket. Over-torquing a wedge anchor spins the cone past its set and kills the holding value, so a calibrated torque wrench is the right tool here rather than an impact gun.
7) What thread does the Trubolt wedge anchor stud take, so I can order matching nuts and washers?
The stud is 1/2-13 UNC, which is standard coarse thread, with 2-3/4 inches of thread on the 4-1/4 inch anchor, 4 inches on the 5-1/2, and 5-1/2 inches on the 7 inch. It is a male threaded stud anchor, so the nut and washer come up against the top of your fixture. Any 1/2-13 nut will thread on, though for exterior work match the galvanized finish to avoid dissimilar-metal corrosion at the joint.
8) Can I use these galvanized wedge anchors outdoors or in a wet area?
The hot-dip galvanized finish is what you want for exterior, damp, or corrosive job-site conditions, and the anchor carries a damp location rating. Hot-dip gives a thicker zinc layer than plain zinc plating, which is why it is the usual pick for rooftop curbs, dock equipment, exterior railings, and anything washed down. For continuously submerged or chloride-heavy service, stainless is the better call.
9) How do I tell the length of a Trubolt anchor after it is installed, or sort mixed stock on the job?
Each length carries a stamped length ID code on the anchor: F for the 1/2 x 4-1/4, I for the 1/2 x 5-1/2, and L for the 1/2 x 7. That letter is how an inspector verifies the right anchor went in once the stud is the only thing visible, and it is the fastest way to sort loose anchors that got mixed between boxes.
10) How many Red Head Trubolt galvanized anchors come in a box?
25 anchors per box, one size per box. The three 1/2 inch lengths are ordered separately: WS-1242G for 1/2 x 4-1/4, WS-1254G for 1/2 x 5-1/2, and WS-1270G for 1/2 x 7. Each anchor ships complete with its nut and washer assembled on the stud, so there is nothing extra to buy beyond the 1/2 inch carbide bit.
11) Are Red Head Trubolt wedge anchors made in the USA for a Buy American job?
Red Head Trubolt wedge anchors are made in the USA with US and global materials, and country of origin is listed as United States. For a federally funded project with Buy American or BABA requirements, confirm with your compliance officer whether "US and global materials" satisfies the specific domestic content threshold on your contract.
