Product detail
Wedge expansion anchors for cracked and uncracked concrete, made from 304 stainless steel at A2-70 strength so the fixing keeps its load capacity in damp basements, coastal sites and wash-down areas. The bolt expands as the nut is tightened, clamping the sleeve against the drilled hole, which gives a through-fixing that can be removed and re-used without resin. Six diameters from M6 to M16 cover balustrades, awnings, racking, air-conditioning brackets, machine bases and scaffold ties, with 27 length options from 50 mm to 150 mm so buyers can match slab thickness. The acid-pickled finish leaves a clean silver surface that resists fingerprinting and light chemical attack. A2-70 grade means the stud holds tensile loads of the 700 MPa class without the plating flaking that plated carbon steel suffers outdoors. Supplied in cartons with nuts and washers, and available in mixed-size assortments for distributors building a fastener range.
