Full Weldable Bolt Screw Rebar Coupler

Weldable Bolt Screw Couplers are designed to provide dead end embedment for bars in concrete. This helps to reduce congestion and simplify the placement of rebars by removing the need for hooked ends.

Distinct from pure threaded couplers, this weldable screw coupler is designed for welding connection scenarios. The outer sleeve can be directly welded on steel plates, steel columns or embedded steel parts on construction site. Insert rebar into sleeve hole and lock firmly by tightening side positioning bolts, no requirement for rebar end threading processing. It is an optimal solution for projects where rebar threading cannot be operated.

▎Production & Quality Inspection

Raw steel tubes go through material composition detection before cutting. Bolt holes are positioned and drilled by CNC equipment to guarantee screw matching precision. Finished products take random tension test to confirm locking strength meets international construction acceptance criteria.

▎Packing & Shipment

Regular specifications packed in export cartons, bulk cargo loaded on fumigated wooden pallets. Spot goods deliver within 3–5 working days, non-standard dimension supports OEM customized production.
