newlng Expansion Bolt M8 x80mm Anchor Bolt 304 Stainless Steel Expansion Anchor Bolts Eye Bolts Heavy Duty Eyebolt Expansion Screw for Masonry Concrete Wall 5piece

Specification: M8*80 (bolt diameter 8MM, screw length 80MM) Quantity: 5PCS Made of 304 stainless steel, it is durable and can be used outdoors. It has better rust resistance (can be used in wet or even water, and will not rust). Hole size: Select a percussive drill bit of the same diameter as the expansion screw expansion tube, and install it on the electric drill to drill the wall. The depth of the hole is the same as the length of the bolt. It should be noted that the expansion bolts must be mounted on a relatively hard substrate, and the place where the soft and easy to fall off is unstable, such as the gap of the lime soil of the wall.The expansion tube part should all enter the wall. As long as the threaded part is long enough, the sleeve part is deeper and firmer. The tensile load installed in the concrete is five times that in the brick.After properly installing an M6/M8/M10/M12 expansion bolt in concrete, its tensile load strength is 120kg/170kg/320kg/510kg respectively. 100% customer satisfaction, if you are not satisfied with the product, you can always send us an email to us, provide you with satisfactory service in the first time, you can also get a full refund, please rest assured to buy.
