Premium-Grade Hex Set Screws for Secure Fastening in Construction and Machinery
Discover DMS Fasteners' selection of premium-grade set screws, designed for secure fastening in a wide range of construction and machinery applications. Offering durability, corrosion resistance, and available in various sizes, our set screws come in top-tier metric classes 4.6, 8.8, 10.9, and 12.9, alongside imperial Grades 5 and 8 for unmatched fastening performance. Choose our high-tensile fasteners for reliable, robust connections.
Set Screw Finishes: Zinc Plated vs. Black Oxide
Finish on Set Screws:
The finish of a set screw refers to its surface treatment, which enhances corrosion resistance, appearance, and durability.
- Zinc Plated Finish: Zinc plating adds a protective zinc layer that guards against corrosion. It's ideal for outdoor or moist environments due to its superior corrosion resistance. Common use cases include construction, automotive, and marine applications where the bolts are exposed to the elements.
- Black Oxide Finish: Black oxide provides a black finish whilst maintaining corrosion resistance, primarily used for its visual appeal. It's best for indoor applications where corrosion is less of a concern, such as in home appliances, electronics, and decorative installations.
Metric Class and Imperial Grade Strengths for Set Screws
When selecting set screws, understanding the strength differences between metric classes and imperial grades is crucial for ensuring the integrity of your project.
- Class 4.6: These set screws are made of low or medium carbon steel and have a minimum tensile strength of 400 MPa and a yield strength of 60% of the tensile strength. They are suitable for light applications where high strength is not required, such as securing furniture or light fixtures.
- Class 8.8: A medium carbon steel set screw that's been hardened and tempered, Class 8.8 has a tensile strength of 800 MPa and a yield strength of 80% of the tensile strength. These are appropriate for automotive applications, structural steelwork, and equipment manufacturing.
- Class 10.9: These set screws are alloy steel, quenched and tempered, with a tensile strength of 1,000 MPa and a yield strength of 90% of the tensile strength. They're used in high-stress applications like engine mounts, suspension systems, and heavy equipment where strength is critical.
- Class 12.9: The highest metric class for strength, these alloy steel screws have a tensile strength of 1,200 MPa and a yield strength of 90% of the tensile strength. They are used in precision machinery and applications where the highest strength is necessary, such as in the aerospace industry.
- Grade 5: These set screws are made from medium carbon steel and are quenched and tempered. They have a minimum tensile strength of 120 ksi and are suitable for automotive applications, OEM (original equipment manufacturer) service, and repair where moderate strength is sufficient.
- Grade 8: Made from medium carbon alloy steel and heat-treated, these set screws have a higher tensile strength of 150 ksi. They are used in demanding applications such as vehicle suspensions, heavy equipment, and industrial machinery where high tensile strength is a must.
Use Cases for Set Screws:
- Machine Assembly: Set screws are crucial for securing parts onto a shaft or within a housing without the need for a protruding head, ensuring smooth operation and safety.
- Adjustable Equipment: Ideal for creating adjustable connections in gym equipment, allowing for easy adjustments while ensuring stability and strength.
- Precision Instruments: Used in the assembly of precision instruments where a flush finish is necessary to maintain the integrity and accuracy of the device.
- Furniture Manufacturing: Provide a secure fastening solution in furniture manufacturing, especially in knock-down furniture, allowing for easy assembly and disassembly.
Our set screws are engineered to meet the demands of any project, providing the strength and reliability needed for secure fastening. Whether you're working on heavy machinery, precision equipment, or general construction, our selection offers the perfect solution for every application.
