SERVICE

Verifies that each screw meets specified measurements, including length, diameter, thread pitch, and tolerances to ensure every screw meets dimensional specifications.

Projects a magnified outline of the screw to inspect thread profile, angles, and geometric accuracy that cannot be easily measured by calipers.

Measures surface and core hardness to verify heat treatment quality, consistency, and resistance to deformation.

Evaluates torque resistance and the screw’s resistance to bending or deformation under lateral force.

Measures the torque required to drive the screw into test material to ensure stable installation and prevent over-torque failure.  

Applies axial force to determine the maximum load a screw can withstand before breaking, confirming structural strength.

Measures drilling speed and efficiency to ensure self-drilling screws perform effectively in metal or wood substrates.

Evaluates the screw’s pneumatic penetration ability by measuring how effectively compressed air can drive the screw through test materials, ensuring consistent penetration performance in automated or high-speed fastening applications.

Evaluates coating color consistency by comparing screws against customer samples and checking color variations between different production batches. The test ensures uniform appearance, accurate color matching, and stable coating quality under standardized lighting conditions.

Painted screw heads are exposed to ultraviolet light to evaluate coating durability and color stability.The test measures how many hours the painted surface can withstand UV exposure before visible discoloration occurs, ensuring reliable coating performance for long-term outdoor applications.

Employs X-ray technology to precisely measure the thickness of surface coatings, ensuring proper corrosion protection and coating uniformity. 

Simulates corrosive environments to evaluate long-term rust and coating durability.
