What are Bumax Torx Countersunk Screws?

Bumax Torx Countersunk Screws are innovative, high-grade fasteners, integral to the comprehensive array of precision engineering screws. These screws are characterised by a conical-shaped upper half, also known as a countersunk head, which enables a flush fit with the material surface once installed. The driving mechanism utilises a star-shaped Torx pattern, designed to handle higher torque compared to traditional screw drives, thereby offering superior control and reduced risk of stripping during high-torque applications.

How Bumax Torx Countersunk Screws Work.

In terms of operational mechanics, Bumax Torx Countersunk Screws mate with a corresponding thread that could be present in a nut or a pre-tapped hole in the workpiece. Upon tightening, the countersunk head design of the screw enables it to sink into the material, providing a smooth and clean surface finish, free of any protrusions. The unique Torx drive system increases the surface area in contact with the driver, leading to enhanced torque transmission. Given the exceptional durability and tensile strength of Bumax 88 material, these screws stand up to the demands of critical and high-stress environments.

What Material Bumax Torx Countersunk Screws Are Made From.

The prime component in the construction of Bumax Torx Countersunk Screws is Bumax 88, a variant of high-strength stainless steel. Bumax 88 possesses low carbon content, which translates to minimal carbide precipitation and enhanced resistance to intergranular corrosion. Moreover, the excellent mechanical properties of Bumax 88, such as high tensile strength and good ductility, make these screws perfect for high-load applications and challenging environments.

What Size and Type Bumax Torx Countersunk Screws Are Available.

Keeping up with the diverse demands of precision engineering, Bumax Torx Countersunk Screws at Accu are available in the popular metric sizes of M8 (8mm) to M10 (10mm) and in lengths ranging from 10mm to 150mm. This selection caters to an array of engineering needs, including high-stress applications and those requiring a streamlined, flush surface. If your project demands a different type of screw, we encourage you to explore other precision screws like Socket Head Screws or Torx Cap Head Screws for broader design options.


Q: What distinguishes Bumax Torx Countersunk Screws from other fasteners?.

A: Bumax Torx Countersunk Screws provide a unique blend of high tensile strength, courtesy of Bumax 88 stainless steel, and superior torque transmission through the Torx drive system. The countersunk design enables a flush fit with the surface, delivering a smooth, clean finish in the final assembly.

Q: Can Bumax Torx Countersunk Screws handle corrosive environments?.

A: Yes, they are exceptionally capable in this regard. Bumax 88, the stainless steel variant used in these screws, exhibits excellent corrosion resistance, making these screws an ideal choice for applications in corrosive or harsh environmental conditions.

Q: What tool do I need for Bumax Torx Countersunk Screws?.

A: You will require a Torx driver or bit that corresponds to the Torx size of the screw. Accu offers a wide range of Torx drivers and bits suitable for all your installation needs.

Q: How do I select the correct size of Bumax Torx Countersunk Screw for my project?.

A: Determining the right screw size hinges on the specifics of your application, which could include factors like material thickness, load-bearing capacity, and the dimensions of pre-drilled holes or nuts. At Accu, we offer Bumax Torx Countersunk Screws in M8 and M10 sizes, catering to a multitude of engineering requirements.

Q: Is there a minimum order requirement for Bumax Torx Countersunk Screws at Accu?.

A: At Accu, we maintain a customer-friendly approach. We accommodate orders ranging from a single Bumax Torx Countersunk Screw to orders in the thousands, catering to all your precision engineering component requirements, irrespective of size or scale.
