Enhance assembly efficiency with ergonomic fastening solutions
In any assembly process—whether manual, semi-automated, or fully automated—efficiency, reliability, and ease of use are critical. Traditional fastening solutions often lead to worker fatigue, assembly inefficiencies, and costly defects like cross-threading.
Ergonomic screws are one of the important factors that help reduce physical strain, improve tool engagement, and enhance overall assembly performance. By selecting the right screw technology, manufacturers can benefit from:
- Increased productivity
- Reduced downtime
- Lower overall costs
We offer a range of ergonomic screw solutions tailored to different assembly processes:
1. Ergonomic solutions for manual or semi-automated assemblies
Repeated movements increase worker fatigue and can eventually lead to injuries, ultimately affecting efficiency. This is especially common in the following situations:
✕ Constantly applying end-load on the screwdriver to keep the bit engaged with the screw recess.
✕ Extra effort required to install the screw in place.
✕ Additional time, effort, and cost needed to install washers, nuts, or other locking elements.
Reduce worker fatigue
Ergonomic Screw Drive System - TORX PLUS®
The screw drive plays a critical role in transmitting clamping force to assembled parts. The TORX PLUS® screw drive system is a proven solution that enhances assembly line performance, improves product reliability, and reduces total assembly costs. Here is why:
- Reduces worker fatigue – Eliminates the need for end-load pressure to keep the driver engaged in the recess.
- Prevents cam-out and tool slippage – Eliminates cam-out effects and ensures perfect engagement, preventing damage to fasteners and surrounding surfaces.
- Achieves desired clamp load – Optimizes torque transmission and eliminates radial force that can stress fastener recesses.
- Enables faster tool engagement – Large cross-sectional areas allow faster tool engagement, maximizes torque transfer and increases torsional strength.
Avoid cross-threading problem
Ergonomic Screw Point - MAThread®
Cross-threading is a common problem when using metric screws in pre-tapped holes. Cross-threading requires rework, leading to delays and increased costs. MAThread® is an efficient solution to the problem of cross-threading in pre-tapped holes. By allowing the screw to align easily with the nut member, it eliminates the need for excessive effort and time during insertion.
The MAThread® point engages with optimal interference in the nut, automatically straightening the screw by up to 15°. It is the best alternative to the standard Dog Point, offering superior performance.
Compared to the standard Dog Point, MAThread® achieves 100% success in alignment, ensuring a smoother and more reliable assembly process.
Easy thread forming screws insertion
Ergonomic Screw Thread - TAPTITE 2000®
TAPTITE 2000® thread-forming screws provide an ergonomic solution for metal assemblies. Their specialized thread design requires less torque for thread forming and fastening, reducing worker effort and improving efficiency.
The progressive point ensures excellent axial alignment and requires very low end load, making thread formation easier.
With excellent mechanical properties, TAPTITE 2000® screws eliminate the need for tapping operations and additional locking elements while also preventing cross-threading.

2. Ergonomic solutions for fully-automated assemblies
Manufacturers are constantly striving to increase efficiency within shorter timeframes. At the same time, reducing energy consumption is essential to meet environmental standards and improve cost-effectiveness.
Increase assembly efficiency
Ergonomic Drivce System - TORX PLUS® AUTOSERT®
TORX PLUS® AUTOSERT® ensures perfect engagement at high speeds. Laboratory tests have shown 100% successful screw engagement at drive bit speeds of up to 700 RPM.
The larger cross-sectional area and elliptical design increase the contact surface, maximizing engagement between the driver and fastener. This extends tool life and ultimately reduces costs and downtime associated with bit replacement.

Ensure screw designs fit your assembly line
Application Engineering Supports
In fully automated assembly, screw head design is crucial for smooth installation. Our Application Engineers ensure a stable head radius and cylindrical shape so that the robot can securely hold the screws.
Additionally, good concentricity is essential—the screw head must share the same axis as the screw shank to ensure proper alignment and smooth operation.
