M12 Stainless Steel Expansion Hook 5 Pack For Concrete Brick Indoor Outdoor

M12 expansion hook for concrete and brick anchoring, designed for homeowners, contractors, and DIY users securing anti theft doors and windows, air conditioning units, fences, rain awnings, and general home improvement or rigging hardware indoors and outdoors. The hook body is 304 stainless steel with an M12 threaded expansion mechanism: tightening the thread pulls a tapered cone so the sleeve expands outward against the drilled hole wall for a firm hold. Because the sleeve presses against the hole wall instead of relying on the thread alone, it holds steady in solid concrete and brick for fences, awnings, and door or window frames. 304 stainless steel resists corrosion and wear in damp indoor and outdoor areas such as bathrooms, basements, and coastal sheds, so holding strength lasts on door, window, and air conditioning brackets rather than rusting like plain carbon steel. It suits solid concrete and brick only; it is not intended for overhead lifting, human suspension, soft drywall, hollow brick, or holes wider than the sleeve, and it is not a substitute for certified structural anchors in load bearing walls. Installation: drill a matched hole, insert the hook, tighten the thread so the cone pulls the sleeve outward against the hole wall. Wipe with a dry cloth to maintain the surface. Manual measurement tolerance is 1 to 2 mm (0.04 to 0.08 in); verify hole size and load needs before ordering. Specifications:
