This anchor is\ndesigned for use in Concrete, Block, and Brick. Environment The anchor is\ndesigned for use in a Dry environment. Head Style The anchor is a Hex Washer\nhead and is designed to allow the head to sit on top of the surface of the\nitem being attached. Hole Diameter\/Bit Diameter The anchor requires a 5\/32\"\nhole to be drilled in the base material (Concrete, Block, and Brick). The hole\nshould be drilled with carbide tipped bit that meets ANSI standards and used\nin a hammer drill. Driver Required A 1\/4\" nut driver is required for driving\nthe anchor into the base material. Diameter of Anchor The diameter of the\nanchor is 3\/16\". Length Anchor The length of the anchor is 3-1\/4\" Thread\nLength The length of the threads on the anchor is 1-3\/4\" in length. Minimum\nEmbedment The minimum anchor embedment into the concrete is 1\". Therefore, the\nanchor must be installed so that a minimum of 1\" of the anchor is embedded\ninto the concrete. Maximum Fixture Thickness The maximum fixture thickness or\nthe maximum thickness of the material being fastened for a anchor is 1-3\/4\" to\n2-1\/4\". This will ensure that the minimum embedment of 1\" will be met. Fixture\nHole Diameter The hole in the fixture or material being fastened must be\nlarger than the designated diameter of the anchor. The 3\/16\" diameter anchor\nrequires the hole in the fixture to be 1\/4\". Spacing between Anchors Each\nanchor must be spaced a minimum distance of 3\" from each other when measured\ncenter to center. Edge Distance It is very important not to install the anchor\nany closer than 2-1\/4\" from an unsupported edge of the concrete.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eBIT INCLUDED IN EACH BOX-Proper bit equals improved holding values and reduced cost\u003c\/li\u003e\n \u003cli\u003eSLOTTED HEX HEAD-Can be driven with a nut driver\u003c\/li\u003e\n \u003cli\u003eSELF-TAPPING-Taps threads directly into masonry and requires no other anchor\u003c\/li\u003e\n \u003cli\u003eDIAMOND POINT-Easier to drive the screw to save time\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-07-16T17:01:58+10:00","created_at":"2026-07-14T18:00:45+10:00","vendor":"CONFAST","type":"Concrete Screws","tags":["home_improvement_July2026"],"price":20000,"price_min":20000,"price_max":20000,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":58176879329440,"title":"3\/16\" x 3-1\/4\"","option1":"3\/16\" x 3-1\/4\"","option2":null,"option3":null,"sku":"B072343VFT","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"CONFAST 3\/16\" x 3-1\/4\" Hex Head Concrete Screw Anchor with Drill Bit for Anchoring to Masonry, Block or Brick (100 per Box) 3\/16\" x 3-1\/4\" -
