Plastite® 45 Thread-Forming Fastener0 pages

P L A S T I T E ® 4 5 T H R E A D - F O R M I N G FA S T E N E R
The Plastite® 45 fastener is designed
45°
thread
profile

to facilitate thread-forming in
less-compressable plastics while

45°

providing high resistance to
strip-out and pull-out. It has smaller
root and major diameters than a 48°
Plastite, so it can be used in smaller
bosses.

Plastite® 45 Fastener

KEY ADVANTAGES
• Can be used in smaller bosses than Plastite 48 fasteners
• Increases product reliability
• Lowers required drive torque when fastening stiffer
thermoplastics

FEATURES & BENEFITS
Tri-roundular configuration allows displaced material to cold
flow back into relief areas
• Minimizes radial stress

SPECIFICATIONS

• Reduces possibility of boss
failure

relief areas

thread-forming
lobes

Sizes • #2 – 3/8" (metric sizes 2 – 8);
other sizes may be available upon
request

• Eliminates need for inserts and
lock washers

Head Styles • Can be used with any
external or internal head designs;
pan, hex washer, and flat styles
standard

45° thread profile allows threads to penetrate deeply into
plastic material
• Generates strong mating threads

Drive System • Can use any system,
including TORX PLUS® Drive

• Increases resistance to strip-out

Finish • As required

APPLICATIONS
Engineering-grade thermoplastics
(with a flexural modulus over 850,000
p.s.i.)

• Allows design of thinner bosses

• Resists vibration loosening
• Achieves wide differentials between drive and fail torque
Single lead design and narrow helix angle lowers drive
torque and failure torque in thermoplastics with a flexural
modulus over 850,000 p.s.i.
• Creates less stress on the boss
