Performance of REMFORM® Screws by Plastic Type
Choosing the right screw is critical when working with different plastic materials.
The graph below illustrates the relationship between insertion force and pull-out resistance for various thermoplastics when using REMFORM® screws.
This visual guide helps engineers and buyers identify the most suitable fastening solution based on the material used in their application.
This technical chart helps you select the ideal CELO screw based on the mechanical characteristics of the plastic you're working with.
REMFORM® screw is best suited for flexible and low-modulus plastics like PE, PP, ABS, and ASA.
REMFORM® II HS™ screw is ideal for medium-stiffness materials, such as POM+30GF or PA6+30GF.
REMFORM® II F™ screw is recommended for high-rigidity and glass-filled materials such as PPA+40GF or PPS+40GF.
By matching the screw to the modulus values of the plastic, you improve fastening strength, reduce risk of cracking, and optimize assembly reliability.
The table below offers a guide to select the screw to be use based on the type of plastic. Field tests will determine the optimal solution based on hole geometry, mechanical requirements and installation parameters.
The type of plastic is determined by its Bending Modulus (Flexural Modulus):
- Ductile plastics < 1,900 MPa (< 275,571 psi): REMFORM® screw
- Medium plastics 1,900 - 2,999 MPa (275,571 - 434,968 psi): REMFORM® screw
- Hard plastics 3,000 - 6,850 MPa (435,113 - 993,508 psi): REMFORM® II HS™ screw
- Very Hard plastics > 6,850 MPa (> 993,508 psi): REMFORM® II HS™ or REMFORM® II F™ screw
- Thermoset materials: REMFORM® II F™ screw
- Hard plastic and Low Thickness pieces: PCB screw
- Soft plastic and Low Thickness pieces: TWINPLAST screw

Expert assistance and custom solutions
An optimal screw solution to be applied on plastic materials requires a detailed attention to the overall assembly process. Using standard self tapping screws is frequently causing assembly problems since plastic material is liable to burst due to stress during the assembly. We work in cooperation with our customers to find the best solution for the assembly on plastic materials, by analyzing plastic types, boss configurations, mechanical requirements and installation parameters.
Our technicians at CELO test laboratories provide technical reports with valuable data on screw capabilities for specific customer applications. Towards joint analysis and mechanical testing which include screw insertion, threading, failure, loosening torque and pull-out tests, we recommend the optimal solution to best meet your application requirements.
Additionally, to verify that the dimensions of the selected screws conform to your design, CELO offers you the possibility to download the 3D files of our products.

FAQ - Screws for Plastic
It depends on the plastic type and application. Common options include Hi-Lo screws, PT screws, and trilobular thread designs specifically engineered for thermoplastics.
In most cases, yes. The pilot hole size is critical to ensure proper thread engagement without cracking. We can help you calculate the optimal hole diameter: Hole Design Tool
Each plastic has a specific torque threshold. Applying too much torque can damage the material. We offer guidance based on your material and screw type. Talk to an engineer
