Description

Product Overview

The A79 pivot screw serves as the axial fastener and tension adjuster for professional hairdressing shears. It features a disc head with a silver-toned outer ring, centered with a large, polished red gemstone that delivers a rich, vibrant glow. Made from 9Cr18MovCo stainless steel, the disc diameter is 0.40 inches. This fastener connects two shear blades and controls rotational resistance. The vivid red center and silver ring create a bold, elegant look, while the solid disc structure allows easy rotation for tension fine-tuning. It is a premium replacement spare part for barber shears.

Core Function & Usage

This pivot screw is the core connecting and tension adjusting component of hairdressing shears. It joins the two cutting blades together and sets the rotational resistance between blades.

Barbers can turn this screw to fine-tune blade tightness: properly adjusted tension ensures blades open and close smoothly, keeps consistent cutting performance, reduces wear of the cutting edge, and avoids hair pinching during haircutting.

When the original pivot screw gets worn, loose or damaged after long-term salon use, this replacement part can be installed to restore normal working condition of the hair shears.

Disc Head Design: 

Disc head with a silver-toned outer ring and a large red gemstone center. The polished red surface catches the light for a rich, vibrant glow. The contrasting red and silver color scheme adds a bold, elegant touch to the scissors. Solid disc structure prevents hair snagging in daily cutting operation.

Material: 

Constructed from 9Cr18MovCo stainless steel. The material features good hardness, wear resistance and rust resistance, suitable for long-time repeated use in hair salon environments.

Precision Forming: 

Manufactured with tight size tolerance. After installation, the scissors can rotate smoothly without jitter or stuck.

Application Scenarios

Used for replacement and maintenance of professional hair cutting shears. Widely applied in barbershops, hair salons, as well as daily maintenance of personal hairdressing scissors.
