Tapered Coupler Manufacturers in Vellore
As premier tapered coupler manufacturers in Vellore, Leo Industries delivers high-performance mechanical splicing systems known for their reliability and ease of use. Our tapered thread couplers create a full-strength connection between two reinforcing bars. This system involves cutting a precise, metric-tapered thread onto the rebar ends, allowing the coupler to be quickly screwed on. This method ensures that the splice achieves a strength greater than the parent bar itself, critical for high-stress structural applications across Vellore.
Working Principle & Process Flow (Tapered)
The system relies on a **tapered thread** machined onto the rebar ends. This unique design ensures that when the coupler sleeve is hand-tightened and then firmly torqued, the threads on the bar mesh perfectly with the internal threads of the sleeve, creating a secure, self-aligning connection. The slight taper guarantees maximum surface contact and uniform stress distribution across the splice. This process is fast, eliminates concrete congestion, and is easily verifiable on-site by checking the required torque.

Maintenance & Safety Tips
ChecklistLeoindustries
Pre-Installation
Ensure the tapered thread section on the rebar is clean and undamaged
Check the engagement length required for the specific coupler size
Confirm you have a calibrated torque wrench for the final tightening
Installation Practices
Hand-tighten the coupler until snug before using the torque wrench
Apply the specified torque precisely; overtightening should be avoided
Visually confirm the coupler is fully engaged and there are no exposed threads
FAQs — Tapered Couplers
Q1
What makes a tapered coupler superior to a straight thread coupler?
The **tapered thread** is self-aligning and ensures a tighter, more intimate connection, distributing load more uniformly than a straight thread, which helps guarantee full tensile strength.
Q2
Is special equipment needed to prepare the rebar ends?
Yes, a specialized **taper threading machine** is required to cut the precise tapered thread onto the rebar ends before the coupler can be installed.
Q3
Can these couplers be used for positional connections in tight spaces?
Yes, we offer different types of **tapered couplers**, including positional versions (locknut couplers) designed specifically for connections where neither bar can be rotated fully.
Q4
What rebar sizes do you manufacture in Vellore?
We manufacture **tapered couplers** for all standard TMT bar sizes typically used in the Vellore market, ranging from 16mm to 40mm diameter.
Q5
Does the taper coupler reduce the strength of the rebar?
No. When installed correctly, our **tapered coupler** system ensures the final splice strength is greater than or equal to the yield strength of the rebar being joined.
