Introduction
Acument Global Technologies specializes in high-performance fasteners for plastic applications, addressing challenges like ductility, thermal expansion, and clamp retention that standard metal fasteners cannot meet.

Why Special Fasteners for Plastics?
These fasteners provide higher strip-out torque, increased resistance to loosening, and higher pull-out values, reducing costs by allowing thinner bosses and eliminating supplementary locking devices.

Design Considerations
Plastic fasteners have narrower thread profiles (30° to 48°) than standard screws (60°), reducing radial stress and allowing smaller bosses, minimizing damage, and increasing pull-out resistance.

Material Properties
The flexural modulus is crucial for understanding plastic response to fasteners. Fillers and reinforcements affect performance, while thermal expansion and creep are critical as plastics expand faster than metals.

Installation and Testing
Proper seating torque is essential and varies by application. Excessive driver speed can generate heat, compromising joint quality. Testing is recommended for optimal fastening solutions.

Design Issues and Recommendations
Thread engagement and pilot hole diameter are critical. Boss design should consider drafted holes and specific fastener recommendations. Methods to compensate for creep include reducing stress and adding spring elements or metal sleeves.

Standards and Material Compatibility
Fasteners meet various automotive standards. A chart guides fastener selection based on material properties like flexural modulus for compatibility and performance.
