Product description:
·It consists of a screw, a thrust sleeve, a flat washer, a spring washer and a nut. Self-cutting mechanical keying effect, no need for special reaming drills.Application:
·Curtain Wall Embedded Parts Fixing
·Curtain wall keel fixingMaterial:
·Grade 4.8 steel, Grade 5.8 steel, Grade 8.8 steel
Steel, Stainless Steel
304(A2-70)/316(A4-80)
·Surface treatment:
Electro-galvanised, hot-dip galvanisedSubstrate:
·Non-cracked concrete/cracked concrete
·Natural stoneAdvantages:
·Easy to install, reliable performance, can be tightened to the force
·Suitable for fixing at various angles including head-up, suitable for small margin and small pitch installation.
·Self-cutting into the substrate under torsion.
·Almost no expansion stress in the natural environment, to meet the requirements of different burial depths, to ensure effective and tensile strength.Operation process
1、 Use straight hole drill bit to drill the corresponding diameter and depth of the empty
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 self-expanding bottom anchor bolt to make the bottom expand to complete the anchoring

Note:
1、The table data applies: to meet the minimum thickness of the substrate, no margins, spacing affect the correct installation of a single anchor bolt bearing capacity
2、Table data based on C30 substrate concrete, substrate grade changes, should be in accordance with the specification of additional concrete strength impact factor
3、The design value of bearing capacity of the table includes the safety factor of material sub-items.
4、 If you need to know the limit value of load bearing capacity of anchor bolts, you can contact our staff and provide the corresponding test report.
