Product Overview
The A8 pivot screw serves as the axis and tension adjustment part of professional hairdressing shears. It adopts a multi-lobed disc head with serrated outer edge and an embedded red decorative stone at center, made of 9Cr18MovCo stainless steel, with a diameter of 0.43. This screw connects the two blades of hair scissors and controls the tightness of blade rotation. The shaped disc head has a neat appearance, and the serrated outer rim provides better grip for tension adjustment. It is a practical replacement 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:
Low-profile multi-lobed disc head with serrated edge and a red decorative stone in center. The serrated edge provides better grip for tension adjustment. The flat disc structure will not catch or pull hair in normal cutting. The multi-lobed outline and center red stone are decorative design on the screw head without affecting mechanical performance.
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 CNC Machining:
Manufactured by CNC precision machining to maintain stable 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.
