Ergonomic solutions for manual or semi-automated assemblies
Traditional fastening solutions often lead to worker fatigue, assembly inefficiencies, and costly defects like cross-threading.
Repeated movements can eventually cause 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.
- Unwanted torque reaction repetitively transferred to the assembler’s hand.
- Additional time, effort, and cost needed to install washers, nuts, or other locking elements.
Ergonomic screws are one of the key factors that help reduce muscle strain, improve tool engagement, and enhance overall assembly performance. Thanks to their specialized features and design, selecting the right screw allows manufacturers to benefit from:
- Increased productivity
- Reduced downtime
- Lower overall costs
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.
Low thread forming torque
Ergonomic screw thread for metal assemblies - 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.
Ergonomic screw thread for plastic assemblies - REMFORM® II HS™
The narrow angle of the pressure flank in REMFORM® II HS™ screws results in significantly lower thread forming torque, requiring less effort from operators during installation.
The large difference between the thread forming torque and the failure (stripping) torque provides a wide safety window, making it easier for operators to achieve secure fastening without over-tightening.
Additionally, the low radial forces generated during installation minimize the risk of overstressing or cracking plastic parts, improving assembly reliability and reducing the likelihood of rework or scrap.
Ergonomic screw thread for thin metal sheets assemblies - FASTITE® 2000™
The thread design helps the screw align and start straight, making it easier for operators to insert screws quickly and accurately, even in small or untapped holes.
Additionally, the wide window between threading and failure torque allows operators to achieve secure fastening without over-tightening or stripping the threads.
