Wholesale Box of 25 Pcs · 1/2 x 4-Inch Extra-Heavy Structural Sizing · 4-Piece Segmented Steel Expansion Shield · Multi-Layer Yellow Zinc Plated.
Heavy Duty Steel Shield Expansion Anchor Bolts 1/2 x 4 Inch Bulk Box is a commercial-grade high-intensity masonry structural anchoring hardware package engineered for fastening industrial machinery beds, heavy structural steel column bases, commercial escalator frames, and outdoor HVAC multi-split brackets directly into high-psi cured concrete structures, pillars, and solid bridge foundations. Manufactured from premium structural carbon steel blanks treated with an anti-corrosive multi-layer yellow zinc electroplating matrix, it delivers elite shear resistance and massive pull-out threshold safety tolerances under severe vibration stress. Designed with a heavy 4-piece segmented steel expansion sleeve shield that spreads uniformly against concrete internal walls when the hex nut is tensioned down, it achieves an unbreakable, permanent interlocking load anchor. It stands as a top high-volume raw material selection across Bangladesh for building MEP sub-contractors and infrastructure engineering firms.

Great quality Total product. Delivery was quick and packaging was solid. Would buy again.
This commercial bulk hardware anchoring cargo undergoes automated factory count checking and thread alignment verification prior to warehouse tracking dispatch. Return or package structural replacement claims are valid within 7 days of delivery only if the outer factory cardboard box packaging remains entirely unopened, unpunctured, and clean, and out-of-the-box internal shield segment fractures, severe thread cross-stripping, or missing hex nuts/washers from transit are documented upon physical destination arrival.
Does the job well for the price. Happy with the purchase overall — knocked one star for the wait.
