Product Description:
Consisting of screw, flared casing, flat washer, spring washer and nut.
There are 5.8 grade steel, 8.8 grade steel, 304(A2-70)/316(A4-80) stainless steel and other materials available surface treatment (except stainless steel) are:
1、Electro-galvanised (zinc layer thickness >5um), used in general environment;
2、Hot dip galvanised (zinc layer thickness >45um), used in corrosive environments.Product Applications:
Used in non-cracked concrete/cracked concrete, natural stone and other substrates, high loads of structural elements fixed or heavy equipment installation
★Self-expanding mechanical anchors have stable and excellent anchoring performance under high loads, vibration loads and shock loads.
★Mechanical locking, no need to wait for curing time after installation in place, improving construction efficiency.Operation process:
1、Use straight hole drill bit to drill the corresponding diameter and depth of the hole
2、Use the dust blower to blow dust into the hole until no dust overflows from the hole
3、Use hammer drill to hammer down the bottom of the self-expanding paving bolt, so that the bottom of the rise to complete the anchorage
