Bolts

Bolts secure structures, machines, furniture, and vehicles with reliable clamping force that can be tightened, inspected, and replaced over time. From repairs to structural connections, the right bolt delivers strength, alignment, and serviceability that adhesives and welds cannot match. This collection covers hex bolts, carriage bolts, machine bolts, lag bolts, structural bolts, and anchor bolts, plus matching nuts and washers, so you can build, repair, and upgrade with confidence.

Choose materials and finishes that fit the job. Carbon steel bolts in Grades 2, 5, and 8 provide cost-effective strength; alloy steel socket cap screws and Grade 8 structural bolts handle high tensile loads. Stainless steel A2-70 and A4-80 fight corrosion for marine and outdoor use, while hot-dip galvanized and zinc-plated options offer economical protection. Brass and titanium serve specialty applications that need conductivity or high strength-to-weight. Metric classes 8.8, 10.9, and 12.9 sit alongside UNC/UNF inch sizes to suit global equipment.

Match head and drive to your access and appearance needs: hex head for wrenching, socket head for tight spaces, button and flat heads for low profile, flange head for built-in bearing surface. Coarse threads resist galling and assemble quickly; fine threads give higher clamp precision in hard materials. Select shank length for full joint engagement, and use washers to distribute load and protect finishes.

For safety and performance, follow torque specs, pair bolts with compatible nuts, and add locking methods—nylock nuts, serrated flanges, split lock washers, or threadlocker—to handle vibration. Check markings and standards such as ASME, ISO, and DIN to verify grade, pitch, and quality. Stock assortments keep common diameters and lengths on hand, while bulk packs lower project costs. Whether you are outfitting a workshop, maintaining a fleet, or framing a deck, the right bolts, nuts, and washers help you work faster, safer, and with professional results.
