Stainless Steel Square Set Screws with Rounded End GB83
Stainless Steel Square Set Screws with Rounded End GB83 are a critical fastening component ideal for specific torque transmission and positioning applications, especially when aesthetics and functionality are both critical. Designed to conform to GB83 standards, these set screws with a rounded end are engineered from high-quality stainless steel, offering both high corrosion resistance and excellent mechanical strength.
Product Overview
Stainless steel square set screws with a rounded end are specialized fasteners with a square head and a smooth, rounded tip designed to prevent surface damage during installation. Conforming to GB83 standard specifications, these screws are typically used in applications that require secure fastening without marring the surface of the mating component, such as in shafts or couplings. The use of stainless steel makes them ideal for corrosive environments, including the marine, chemical, and food processing industries.

Material Introduction and Manufacturing Process
These GB83 set screws are primarily made from two grades of stainless steel: 304 and 316. Grade 304 is widely used for general-purpose applications, offering excellent performance and cost-effectiveness. Grade 316 provides superior corrosion resistance, making it ideal for aggressive environments.
The manufacturing process involves:
- Cold forging to form the square head.
- Precision thread rolling for exact thread geometry.
- CNC rounding of the ends to prevent component marring.
- Passivation or polishing to enhance corrosion resistance and aesthetic appeal.
- Final inspection and packaging.
Industries and Applications
Stainless Steel Square Set Screws with Rounded End GB83 are widely used in:
- Machine assemblies requiring non-damaging positioning.
- Marine engineering (resist salt corrosion).
- Food processing equipment (hygienic and rust-free).
- Chemical manufacturing plants.
- Precision instruments and small motors.
- Solar mounting systems.
Product Advantages & Competitive Features
Premium Material Selection
We use only high-quality stainless steel like A2 (304) and A4 (316) to ensure strength and corrosion resistance under challenging conditions.
