The Parallel Thread Rebar Coupler(reinforcement bar connectors)is used for Mechanical Bar Splicing(14mm-40mm) in construction with high strength.

Basic Information or Parallel Thread Rebar coupler

1.Size: 14mm-40mm. in all size

2.Raw Material:45# high-quality carbon structural steel.

3.Type: Standard Type, Left-Handed&Right-Handed Type, Reducing Type.

4.Tensile strength could reach 110% of parent material.

5.Suitable Rebar: HRB335,HRB400,HRB500 and Equivalent Rebars.

Relate Test of Parallel Thread Rebar coupler:

1.Tensile Strength=1.1*Tensile Strength of Rebar (Usually more than 600Mpa)

2.Fatigue Test: After 2 million times of fatigue strength test, connection is in good condition

Rebar thread rolling machine working principle, more details here:

1, reinforced clamping structure: using positive and negative ball screw thread make clamps sliding by mode of self-centering.

2, thread head processing: clamping reinforced,then turn head and axially feed to complete threads processing. Peel rib rolling head turns by the main motor to reducer with rotational speed of 50 r/min. the feeding is completed through the operator pull the handle,there is a course from gears,rack drive reducer and peel rib rolling thread head along the slide bar movement

3 thread rolling wheel, composed by 3 pieces, interchangeable installation.

4 feeding and backing system: press the main motor button, motor make reducer and stripped rib rolling turns heads turning , the operator pull the handle to reach feeding. Threaded processing is completed, travel switch contact press switch button, reverse returned to the starting position after delay and automaticlly stop.

Product Advantages of Parallel Threaded Rebar coupler:

• The raw material is 45# high-quality carbon structural steel.
• Strict quality control. self-inspection, exchange inspection, sample inspection , 100% inspection etc. reject rate lower than 0.6%.
• Tensile strength could reach 800 to 900Mpa. Normal steel,for example, HRB335,the tensile strength reaches 500.5Mpa is OK.
• Our rebar couplers are suitable for steels of different countries.
• We could pack the goods according to customer's special request.
• Simple to operate.
