Discover more about the Left Hand Metric Socket Button Head Screws range.

Left Hand Metric Socket Button Head Screws are specialised fasteners designed with a left-hand thread configuration, meaning they tighten counter-clockwise. Featuring a rounded, low-profile button head and a hex socket drive, these screws are ideal for assemblies requiring a secure and sleek fastening solution with reverse-thread functionality.

How Left Hand Metric Socket Button Head Screws Work

These screws are designed with left-hand threads, providing a secure fastening option in assemblies subject to rotational forces that could loosen standard right-hand threads. The button head design ensures a smooth, low-profile finish, making them suitable for exposed or compact applications. The hex socket drive allows for precise torque application, ensuring a reliable and secure fit.

The Materials Left Hand Metric Socket Button Head Screws Are Made From

These screws are available in two corrosion-resistant materials:

A4 Stainless Steel: Offers exceptional resistance to harsh environments, including marine and chemical exposure.
A2 Stainless Steel: A versatile option for general-purpose applications, providing excellent strength and durability.

Both materials are highly resistant to wear and corrosion, ensuring reliable performance across various industries.

The Sizes and Types of Left Hand Metric Socket Button Head Screws Available

Left Hand Metric Socket Button Head Screws are available in thread sizes ranging from M3 to M6, catering to smaller precision applications. Their left-hand thread design and compact button head make them ideal for use in specialised assemblies and environments where traditional right-hand threads are not suitable.

FAQs

Q: Why Use Left-Hand Thread Screws?
A: Left-hand threads tighten counter-clockwise, making them ideal for applications where rotational forces could loosen standard threads, such as in reverse-threaded machinery or certain motor assemblies.

Q: What Are the Advantages of the Button Head Design?
A: The button head design provides a low-profile finish that reduces the risk of snagging or interference, while offering a sleek, professional appearance for exposed applications.

Q: Can These Screws Be Used in Outdoor or Marine Environments?
A: Yes, both A4 and A2 Stainless Steel are corrosion-resistant, with A4 Stainless Steel being particularly suited to marine and chemically aggressive environments.
