. The dimensions listed are for reference only. Plastite Screws Tri-Round with Type A SMS thread Pan Flat Hex Washer. Drive and strip torques are higher making drive tool adjustments simple.

Find below the list of references available and technical details of our screw for plastic. Plastite trilobular thread rolling screws are designed for high performance fastening in a wide range of thermoplastics. Phillips Pan Hex Wash Phillips Flat CPPP010-----Z1 CSWH010-----Z1 CPFP010-----Z1 Disclaimer.

PLASTITE 48-2 screws in stock Current stock references are included below. Specifically designed screw for use in plastics thermoplastics engineering resins thermosets. The head design can be a hex washer a pan screw head flat and any other internal or external head design.

They can also use different screw drive systems. In addition the screws deep coarsely-spaced threads provide a heavier shear area and deeper. Plastite screws are mainly used in engineering-grade thermoplastics which have a bending modulus of over 850 000 pounds per square inch.

Hex Head Thread-Forming Screws for Plastic Press threads into plastic to create a strong hold. Shorter length engagement will have lower strip out torque and less clamp load Draft Angle. Design of PLASTITEscrews takes full advantage of the cold flow characteristics of many plastics by allowing plastic mate- rial to recover and fill in between the lobes.

It also eliminates the need for lock washers and threaded brass inserts. Main feature of PLASTITE 48-2 screws is the twin-lead thread which increases friction and improves stripping resistance. Thread-Forming Screws for Plastic 18-8 stainless steel screws have good chemical resistance.

Always use trials to determine the optimal hole size and screw length. The PLASTITE screws TRILOBULAR design reduces dangerous hoop stress and the friction of root interference which can frequently cause the bursting of thin-walled bosses. The pressure flanks on threads are engineered to not loosen over time with temperature changes under vibration.

Refer the Plastite Screw guide. PLASTITE TRILOBULAR thread rolling screws were developed specifically for use in plastics. PLASTITE45 screws provide wide differential between drive and fail torques for exceptionally easy drive tool adjustment.

Design Engineering Guide Document No EES-0041 RELEASE 20140512 Threaded Inserts Ultrasonic inserts are. Reduced danger of burst bosses and induced stress. Semblex OLD is currently undergoing maintenance.

Fasteners should have a minimum of 25 times the fastener diameter for length of engagement into the plastic boss. Fasteners specially designed for plastics can optimize performance in specific types of materials. Site Design by.

The two main types of Plastite screws are the 60-1 and the 48-2. The specialized thread profile improves the internal thread quality enhancing holding power and thereby reduces stripping and pull-out and allows for repeated removal and insertion into the same tapped hole. The Boss ID design should have a ½ to 2 degree included draft angle - ½ degree tolerance is typical with a lead in similar to the diagram.

Sizes not listed may be available off the shelf or can be manufactured to customer requirements. SizeTPI The PLASTITE 48-2 screw size designation combines the commonly used numerical screw size with the major diameter Max. Forming screw names are TP30 PT Boss and Plastite.

Designing Threaded Fasteners in Plastic BosScrew A screw for plastics that will not loosen. Trilobe TFS for Metal - Generic alternatives to TAPTITE screws trilobular design allows for lower driving torque eliminates chips and resists vibrational loosening. Steel Flat Head Thread-Forming Screws for Plastic These steel screws are beveled under the head for use in countersunk holes.

The Plastite is the tri-lobular solution for fastening in plastic. Screw Length The thread engagement length should be 20 to 25 times the diameter of the screw. This establishes maximum resistance to vibrational loosening.

D as measured with ordinary micrometers followed by the number of threads per inch. However there are numerous other variations as well. The sharp 48 thread profile increases holding strength and reduces material displacement and boss bursting tendencies.

This fastener can be designed to minimize driving torque but also used where high torque is required. Easy power tool adjustment. After being driven the material fills in around the threads and provides resistance to loosening.

Plastite screws design guide Written By leary Sunday March 27 2022 Add Comment Fastener SuperStores thread guide covers twelve common styles. Our Plastite screws are design especially for abs plastics. They combine a unique TRILOBULAR cross-sectional form with deep wide spaced threads.

Component and boss design should allow for much faster engagement than with single lead screws. The 60 profile on the Type 60-1 screw penetrates deeply into the work piece absorbing higher torques without stripping and resisting pullout forces. 45 thread profile Penetrates deeply into plastic material Reduces possibility of boss failure Increases product reliability Eliminates need for inserts and lock washers Minimizes radial stress Allows design of thinner bosses.

By selecting the proper fastener you may obtain. Hi-Lo A double lead high and low thread form increases performance in low density material. Higher strip-out torque values Increased resistance to loosening Higher pull-out values Reduced In-Place Costs Proper fastener selection may allow the use of thinner.

Recommended for plastics with a flexural modulus up to 850000 psi. The single lead-in design and narrow helical angle lowers the drive torque in abs plastics and also creates far less stress on the mounting bosses. PLASTITE 48-2 TRILOBULAR thread-rolling screws have twin-lead threads to provide faster more efficient insertion in plastic materials.

The smooth burnishing action of PLASTITE thread-rolling screws eliminates the dangers inherent in the use of thread cutting screws. Plastite 45 has smaller root and major diameters than Plastite 48 so it can be used in smaller bosses. For optimal joints in thermoplastics we recommend designing the bore geometry in relation with the screw diameters and materials.

All of our screws have pan heads. Three swaging lobes with full relief of the thread form reduce driving effort and operator fatigue. They are made of carbon steel or stainless steel.
