Wedge anchors expand against the concrete wall when tightened, creating high pull-out strength — they're the go-to for structural fastening (steel posts, heavy equipment, rated tie-downs). Sleeve anchors expand along the full length of the sleeve, distributing load more evenly, and work better in softer concrete or brick. For Houston's clay-soil slabs, wedge anchors are most common for ground-up commercial work; sleeve anchors are preferred for retrofit and masonry.

Wire nut size depends on the gauge and number of conductors being joined. Most pro electricians stock red, yellow, and gray (or blue) nuts: yellow for 2–4 #14 or 2–3 #12 conductors, red for 2–4 #12 or 3–6 #14, gray (small) for low-voltage splices. Brands like Ideal Wing-Nut and 3M Performance Plus print full conductor charts on the box. Tool Mart stocks both jar and case quantities.

Most cartridge adhesives (Loctite PL, Gorilla, Liquid Nails) have a 12-month shelf life from manufacture if unopened and stored at room temperature. Once opened, expect 30–60 days of usable working time. Silicone and polyurethane sealants are similar. Always check the date code printed on the tube — Texas heat in trucks during summer cuts shelf life significantly.

Yes — Tool Mart is built for contractors who buy fasteners by the case, tape by the sleeve, and gloves by the pair-pack of 12. Most high-turn items have tiered pricing for bulk quantities, and we can quote special orders on industrial pack sizes. Walk in to our Houston location or call ahead for a quote on volume orders.
