5 extended bolt batches with strong metal eye rings-closed screw anchor bolts-concrete wall anchor bolts-M10 x 7 cm

Features: These extension bolts are about 10cm in length and are suitable for concrete materials. When the quality of concrete reaches the standard, it can bear a load of 250kg. The drilling depth should be ≥ 7 cm,

Material: These sturdy expansion bolts are made of high-quality, durable, waterproof and wear-resistant alloy. It won't rust, it's safe and firm, it has a large bearing capacity, and it's not easy to deform or break after long-term use.

Easy installation: the expansion bolt is formed by tightening the bolt and pulling the taper, so that the sleeve is close to the borehole wall. Install it on a 16 mm drill bit, and drill holes where it needs to be drilled. In this way, the expansion screw can be easily inserted into the hole, and then tightened and fixed

Application: The W-shaped slope is used to promote the expansion of the expansion screw, and friction is generated to achieve the fixing effect. Usually applicable to house improvement or engineering projects, such as concrete masonry and solid bricks, ceilings, fences, doors and windows, wind, air conditioning devices, etc.

Note: the expansion bolt must be installed on a hard wall or floor. The fixing effect is unstable in soft places and easy to fall, such as cracks in the wall. Please confirm the size before installation, so as to avoid failure of normal use or failure of fixed effect.
