Easy fitting: the self-tapping wood screw thread drives these screw-in cup hooks into timber by hand, without tools or a pilot hole in most softwoods Open C-shaped hook: hang lights, baskets, tools and decorations at the height you need from ceilings and beams, then lift them off in a moment Bright zinc-plated carbon steel: heavy duty cup hooks in 3.5mm to 8.0mm carbon steel with bright zinc plating (BZP), giving sacrificial corrosion protection for indoor and outdoor use, with durable carbon steel for long-lasting, reliable fastening Size and pack: this listing is 45mm x 3.5mm, pack of 5; overall length (L) 45mm, thread diameter (d) 3.5mm, thread length (Lg) 27mm, hook opening (E) 8mm; 5 sizes, 45 x 3.5mm to 80 x 8.0mm, thread diameter rising with length, so the right hook can be matched to lighter or heavier items; the 45mm x 3.5mm and 65mm x 4.0mm sizes are the small screw-in cup hooks for lighter jobs such as ceiling light fixtures, decorations or cable runs Metal wall hooks for timber or masonry: they screw in by hand to timber, or fix into brick, block and masonry with a standard wall plug, so one hook type can cover both a shed or workshop fit-out and a brick or block wall Screw hooks for hanging, indoors or outdoors: ceiling light fixtures from a joist or batten; hanging baskets, flower baskets, pots and planters from a fascia, pergola beam or wall bracket; twine, rope, tools or garden equipment in a garage, shed or workshop; decorations, ornaments or seasonal displays; cables, wiring, extension leads or festoon lights along a wall or ceiling; wooden outdoor structures such as gazebos, pergolas, terraces, patios and decking Packs of 2 to 250: packs of 2, 5, 8, 10, 50, 100, 150 or 250 screw hooks, from a single job to a long run of fixings; the self-tapping thread removes the need for pre-drilling on multi-hook jobs such as cable runs or trellis fixing
