JM Hardware® Concrete Screw Bolt
Industrial Concrete Screws & Bolts – High-Strength, Corrosion-Resistant
On a sunlit jobsite a foreman smiles as each Industrial Concrete screw bites cleanly into stone, locking beams and braces with quiet confidence. Forged for high strength and built to shrug off rust, these corrosion‑resistant screws and bolts deliver a rock‑solid grip that stands up to weather, weight, and time. Quick to install and impossible to doubt, they turn tough builds into lasting landmarks—so your work looks and lasts like true craftsmanship.
Product features
Industrial screws and bolts combine core attributes—high-strength heat-treated steels (carbon, alloy, hardened or stainless) and protective finishes like Zinc, galvanization, Dacromet or Blue/White Ruspert—with extended options in sizes (3/16"–3/4", M6–M20), head styles (hex flange, hex, CSK, flat) and drive types (slotted, Phillips, Torx) to suit diverse installations. Their value and functional attributes include high-low threading, cutting points and Class 10.9/12.9 hardness for exceptional pull-out strength, reliable anchoring in concrete and masonry, and fast, tool-friendly installation that reduces labor and downtime. The product’s engineered geometry and precision thread form a structure that optimizes load distribution, torque control and long-term corrosion resistance for construction, infrastructure and industrial applications, with quality verifiable through lab testing and certification.
