Build Your Custom Solution in 3 Steps

1. Select Your Groove Type – Optimize for Strength or Flexibility

Choose from 10+ engineered groove profiles – from standard V-grooves for general applications to specialized T-slots for heavy machinery.

Our CNC machining ensures ±0.005mm tolerance for perfect load distribution.

Pro Tip:  90% of industrial clients select helical grooves for vibration resistance.

2. Choose Tooth Type: Precision Cutting or Smooth Engagement

Select triangular teeth for high-speed cutting (ideal for aerospace alloys)or rounded teeth to reduce wear in repetitive assembly (common in automotive).

Custom tooth pitch options available – Our engineers recommend 2.5mm pitch for 80% of polymer applications.

3. Design Your Head Shape: Functional Aesthetics Meets Installation Efficiency

From low-profile hex heads (ISO 4762) to tamper-resistant Torx designs, select shapes that align with your tooling ecosystem. 

Pro Tip: 70% of clients pairing button heads with recessed grooves reduce installation time by 40%.

Precision-engineered from concept to delivery: Streamlined 5-stage process with 1-hour response, 72h prototyping, and ISO-certified quality control.
