Polyfast®

EXCEPTIONAL PERFORMANCE AND VERSATILITY… THE POLYFAST® WAY

Polyfast® fasteners are unique thread designs that perform exceptionally in plastic and particle board applications. The asymmetrical thread form and low root diameter provide lower installation torque and efficient fastening. In plastics, this thread design minimizes radial stresses and excessive material displacement, which increases the potential for material cracking. The wide-spaced threads of the Polyfast® design allow additional material to flow between the threads, resulting in higher resistance to pullout forces.

POLYFAST®— ASYMMETRICAL THREAD

DESIGN & PERFORMANCE

• Slim root diameter and low angle of thread reduce installation (drive) torque required.
• Minimizes radial stresses generated during thread forming.
• Asymmetrical thread form efficiently maintains clamp load while minimizing the radial stresses generated.
• High thread profile and unique thread form provide a greater surface area on the thread flank for load distribution.
• Large pitch and high thread profile maximize resistance to pull-out forces.
• Round body design eliminates areas of high stress relative to the fasteners' overall cross-section.
• Gimlet point designs provide unique fade-out thread for optimum starting of the fastener.
