| Acupoint® Anti-Cross-Threading Feature | |||
| | |||
| When a rotating fastener is misaligned with a tapped hole, a no-start condition or cross threading can occur. The Acupoint®feature was developed to overcome both of these assembly problems. As the fastener is driven, the Acupoint® feature locates the tapped hole and provides proper alignment to ensure positive thread engagement | Benefits ■ resists cross-threading and no-start conditions to reduce assembly problems ■ rapid engagement improves productivity ■ compansates for off-angle and off-center conditions | ||
| | |||
| Specifications Thread Design: metric (others on request) | Features ■ truncated spherical point quickly locates te hole to help align the fastener ■ point length minimizes application interference ■ economical design since the point is roll formed ■ point length and diameter designed to avoid thread engagement in misaligned conditions | ||

| Size: 2.5-10mm Head Design: ■ raised head ■ raised countersunk head ■ countersunk head ■ hexacon head (all types also as a round washer head screw) Drive System: ■ cross recess ■ TORX® ■ TORXplus® ■ security drives (all cross recess and TORX® drives are also available as combi drives) Specials: Special variations are available. (double end studs, collar studs, external TORX®, etc.) | Excellent Performance in Off-Angle and OffCenter Conditions During initial laboratory testing, the Acupoint® fastener has shown excellent perfomance in offangle and off-center positions when compared to machine screws. Fasteners with the Acupoint® feature showed a 97% starting rate at an off-angle of 30°. A machine screw had a 0% starting rate at 15°. In the off-center position, the Acupoint® design showed a good start 100% of the time at 2.40 mm off center and 91% at 2.90 mm. Amachine screw demonstrated a 73% starting rate at 2.40 mm and 44% starting rate at 2.90 mm. | ||
