· Thread Form: Full parallel straight thread per JG355/ISO15835
· Size Range: Φ12~40mm full standard specifications
· Material: Tungsten carbide alloy for high hardness
· Matching: Fits standard equal-diameter parallel thread coupler
Designed exclusively for equal-diameter rebar joint processing, BTS parallel chaser forms full standard parallel thread without variable taper, thread dimension strictly follows international construction standards to realize seamless screwing with ordinary equal-diameter rebar couplers. Mainly used for conventional building main reinforcement connection.
Carbide alloy material resists abrasion under long-time continuous processing, stable thread dimension with zero taper error. Unified standard size can interchange among same-type threading machines from different factories, convenient spare part stock management for processing yards.
Single set packed anti-rust, bulk pallet export packaging, in-stock quick shipment.
High-rise residential, municipal bridge regular equal-diameter rebar threading
1.Can parallel chaser make reducing transition thread?
No, parallel type only for equal-diameter standard thread, choose taper chaser for variable size transition.
BTS carbide parallel chaser manufactures standard equal-diameter parallel rebar thread matching regular parallel thread couplers for general civil construction.
