Anchor Bolt is one kind of hollow anchor bolt that use steel expansion shell head to do prestressed to the anchor bolt in advance, it can meet support projects which need to impose certain prestressed. Features of prestressed hollow grouting anchor bolt: 1. Rapid initial supporting, control the deformation of surrounding rock, ensure the stability of surrounding rock. 2. Hollow design and make the anchor achieve the function of grouting pipe, avoid the loss of mortar when the grouting pipe is pulled out by traditional construction techniques. 3. Full grouting and pressure grouting to improve the quality of the project. 4. Because of the role of accessories, the center of the rod is very good, the mortar can wrapped the whole length of anchor rod in order to avoid the risk of corrosion, so that can achieve the purpose of long-term support. 5. Easy to install, without processing thread on-site that you can easily install the plate and nut. Applications: For the anchoring of hard rock; Used as the anchor of tunnel system; Prevention and management of rock burst; Slope treatment; Engineering disease management.Product Name:Coal mining toolsDescription:rock drilling tools, construction drilling tools, mining tools, road milling tools, shield cutters and other related products.Material:carbide steelMOQ:100PCSTypeKTU76, KTU82, KTU84, KTU85, KTU92, KTU94, KTU95, KTU118, KTB47K17H, KTB47K19H, KTB47K22H, KTB43K, KTB43H, KTBHR73 etc and coal bolting bit and coal bolting rod.Diameter19-70mmUseMining and drillingColorAccording to the customer request
