More corrosion resistant than 18-8 stainless steel screws these have excellent resistance to chemicals and salt water. Form design provides full relief for easy driving and effective resistance to vibrational loosening.

Plastite 45 Acument Global Technologies

Minimal radial stress 3.

. Refer the Plastite Screw guide. Design of PLASTITE screws takes full advantage of the cold flow characteristics of many plastics by allowing plastic mate-rial to recover and fill in between the lobes. Screws For Plastics 17.

Specifically designed screw for use in plastics. The standard screw has a safety margin of only 35 lbsin. The 60 profile on the Type 60-1 screw penetrates deeply into the work piece absorbing higher torques without stripping and resisting pullout forces.

PLASTITE screws are legacy products and have been superseded by REMFORM II HS screws. In moderately stiff materials you should start with a hole size that is 75 to 80 thread engagement. For optimal joints in thermoplastics we recommend designing the bore geometry in relation with the screw diameters and materials.

A common option for tiny screws hi-low. The JCPLAS screw uses this design form which provides many benefits like. Screws for Static Joints Plastic Flex Thread Thread Boss Modulus Forming Cutting High-Low Tapping Material psiƒ Screws Screws Screws Screw Soft.

Thread forming begins 2. The 45 thread profile allows threads to penetrate deeply into plastic material and generate strong mating threads which. Super-Corrosion-Resistant 316 Stainless Steel PhillipsRounded Head Thread-Forming Screws for Plastic.

The chosen seating torque was 65 of the failure torque based on testing. Strip-out torque level met or exceeded. Were Here To Help.

Tunable torque design allows screws to be shipped in the Field Ready position. The special fastener for plastic has a safety margin of 12 lbsin. PLASTITE TRILOBULAR thread-rolling screws were developed specifically for use in plastics.

The Plastite 45 screw is designed to facilitate thread-forming in less-compressible plastics while providing high resistance to strip-out and pull-out. Plastite Tri-lobular thread rolling screw for. Ad Call Us For Any Questions You May Have.

Screws for Plastic Design Guide Considerations. Design provides resistance to loosening. As threads are formed the plastic material recovers and fills in around the tri-lobular threads providing.

Angle Gage Block Sets. We keep inch series in stock and produce as custom-made product. Tri-lobe thread rolling screw having twin lead thread design.

This establishes maximum resistance to vibrational loosening. PLASTITE 45 screws provide wide differential between drive and fail torques for exceptionally easy drive tool adjustment. In addition the screws deep coarsely-spaced threads provide a heavier shear area and deeper.

Design is critical to joint integrity and will be discussed in the following paragraphs. Can absorb high torque. Users can also drive the screws deep into harder plastics.

Screw Length The thread engagement length should be 20 to 25 times the diameter of the screw. Inserting the screws into metal inserts overcomes the problems but adds to the procurement and assembly costs. Better quality threadsThe smooth burnishing action of PLASTITE thread-rolling screws eliminates the dangers.

Calculated at a depth equal to half of the fasteners total length of engagement. Fastening plastics using standard self tapping screws frequently causes assembly problems. Tips for investigating a Fastener Problem.

Screws are manufactured to nominal inch and metric diameters. The 60 profile on the Type 60-1 screw penetrates deeply into the work piece absorbing higher torques without stripping and resisting pullout forces. Plastite trilobular thread rolling screws are designed for high performance fastening in a wide range of thermoplastics.

The sharp 48 thread profile increases holding strength and reduces material displacement and boss bursting tendencies. 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. WCL has 50 years of experience with all types of standard and engineered fasteners and provides a comprehensive line of fastener products for sale from some of the worlds leading manufacturers.

Clamp load generated 3. Low thread forming torque ensuring safety of the plastic recipient 5. 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.

Always use trials to determine the optimal hole size and screw length. Plastite tri-lobular thread rolling screws are designed for high performance fastening in a wide range of thermoplastics. The single-lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics.

Drive and strip torques are higher making drive tool adjustments simple. PLASTITE 48-2 TRILOBULAR thread-rolling screws have twin lead threads to provide faster more efficient insertion. A curve added to the helix of the threads keeps the screw secure for life eliminating prevailing torque nuts nylon patches.

Considerably increased durability of screw connection in static and dynamic tensile loading. They combine a unique TRILOBULAR cross-sectional form with deep wide spaced threads. Screw head in contact with plastic.

Deep and narrow 48 degree thread profile and extra wide spacing between threads and a 1-2 thread tapered point. The spacing between the threads is also designed to hold the screw in place and reduce vibrational loosening. The plastic material is liable to burst due to stresses that build up in the assembly.

Optimal connection of plastic parts 2. Elimination of the risk of relaxation 6. These custom screws for plastics are specifically designed with widely spaced threads to drive into materials with ease.

The smooth burnishing action of PLASTITE thread-rolling screws eliminates the dangers inherent in the use of thread cutting screws. PLASTITE Screws Reduced hoop stressThe PLASTITE screws TRILOBULAR design reduces dangerous hoop stress and the friction of root interference which can frequently cause the bursting of thin-walled bosses. TFS for Plastics - Generic alternatives to PLASTITE screws they also feature a trilobular design with.
