What are Imperial Torx Shoulder Screws?

Imperial Torx Shoulder Screws, known for their high-precision fastening capabilities, are categorised under precision screws. What sets them apart is their Torx drive, a six-point star-shaped drive that provides increased torque transmission and avoids the issue of driver slippage - a valuable asset in high-torque applications. With an unthreaded 'shoulder' between the head and thread, these screws act as dowels for assemblies, enabling precise rotational or sliding movements within the assembled parts, a critical feature in precision engineering.

How Imperial Torx Shoulder Screws Work.

Imperial Torx Shoulder Screws work by engaging their threads with a complementary thread either within an imperial nut or pre-tapped hole. The distinctive unthreaded 'shoulder' of the screw acts as a fulcrum or axis, permitting precision movements of components around it. This design function, coupled with the high torque transmission offered by the Torx drive, provides a fastening solution that excels in applications demanding both secure fastening and fine-tuned mechanical articulation.

What Material Imperial Torx Shoulder Screws Are Made From.

Our Imperial Torx Shoulder Screws are crafted from A2 Stainless Steel for standard applications requiring good corrosion resistance and durability. For applications exposed to harsher environmental conditions, such as marine or chemical industries, we offer A4 Marine Grade Stainless Steel variants, known for their superior resistance to pitting and crevice corrosion. For added aesthetic appeal or further protection, our AccuBlack finish is available, enhancing both the visual and functional aspects of the screw.

What Size and Type Imperial Torx Shoulder Screws Are Available.

With a range spanning from the smaller 4-40 thread size, ideal for intricate precision applications, to the more substantial 10-32 thread size, suited for tasks requiring higher load-bearing capacity we provide Imperial Torx Shoulder Screws to cater to a vast spectrum of engineering demands. Our range also consists of shoulder diameters ranging between 1/8 and 1/4 inch and shoulder lengths from 1/8 inch to 1 inch.


Q: What makes Imperial Torx Shoulder Screws preferable in precision engineering tasks?.

A: The combination of Torx drive and the unthreaded shoulder allows for high torque transmission and precise alignment of components respectively, making Imperial Torx Shoulder Screws ideal for applications that demand accuracy and robust fastening in imperial scenarios.

Q: Can Imperial Torx Shoulder Screws resist outdoor and marine environmental conditions?.

A: Indeed, when manufactured with A4 Marine Grade Stainless Steel, these screws demonstrate exceptional resistance to salt water and other corrosive conditions, making them fit for marine and other harsh environmental applications.

Q: What tools are required to install Imperial Torx Shoulder Screws?.

A: Torx drivers or Torx bits that match the size of the screw's Torx drive are needed to install Imperial Torx Shoulder Screws, ensuring an efficient and secure installation.

Q: How to select the suitable Imperial Torx Shoulder Screw for my application?.

A: Factors such as load requirements, environmental conditions, the nature of materials being fastened, and the dimensional specifications of your application, including the imperial size of pre-tapped holes or nuts, guide the selection of the right Imperial Torx Shoulder Screw.

Q: Is there a minimum order quantity for Imperial Torx Shoulder Screws at Accu?.

A: No, at Accu, we cater to all scales of projects, providing flexibility to order a single unit or in bulk, offering optimal solutions for both small-scale precision tasks and larger industrial applications.
