Discover more about the Made To Order Imperial Socket Shoulder Screws range.

Made to order imperial socket shoulder screws are high-precision fasteners engineered for assemblies requiring precise alignment and dependable spacing. Unlike our regular selection of shoulder screws, these fasteners are manufactured specifically upon request, allowing for tailored shoulder lengths in incremental steps to suit exacting application needs.

This custom approach makes them ideal for engineering projects where dimensional tolerances are crucial. Commonly found in fine mechanical systems and high-precision assemblies, these screws provide both stability and accurate component positioning.

How Made To Order Imperial Socket Shoulder Screws Work

Each screw is designed with a smooth, unthreaded shoulder between the hexagonal socket head and the threaded shank. This shoulder serves as a rotating or sliding axis, offering low-friction movement for mated components. As they are custom-manufactured to order, each screw is produced to match exact specifications, guaranteeing a precise fit and exceptional performance.

While production requires a brief lead time, typically around one week, this short delay enables engineers to achieve a higher degree of accuracy and more choice for project designers.

Materials Made To Order Imperial Socket Shoulder Screws Are Made From

Accu’s made to order imperial socket shoulder screws are available in stainless steel (A1), stainless steel (A4) and high-strength steel.

A1 stainless steel provides dependable corrosion resistance, making it a strong choice for general engineering use. For applications exposed to more aggressive environments, A4 stainless steel offers marine-grade durability.

Where high mechanical load is a priority and corrosion resistance is secondary, steel variants deliver the required strength.

Each material can be selected with either a raw finish or a black oxide coating to suit specific application needs.

Sizes and Types of Made To Order Imperial Socket Shoulder Screws Available

These made to order imperial shoulder screws are available across a comprehensive range of specifications. Thread sizes span from 0-80 UNF up to 7/8-9 UNC, with thread pitch options ranging from 9 TPI to 80 TPI.

Shoulder diameters and lengths can be specified in metric units with fine-grain customisation, allowing precise control over your assembly dimensions.

FAQs

Q: What is the typical lead time for made to order shoulder screws?

A: Usually around one week. This allows for thorough customisation options while maintaining high production standards.

Q: Can I order shoulder screws with non-standard dimensions?

A: Absolutely. Although this category covers a wide selection, our screw builder tool allows full customisation to match unique design requirements.

Q: What applications are these shoulder screws suitable for?

A: These screws are ideal for precision mechanisms in aerospace, robotics and instrumentation. They are particularly useful in assemblies requiring a rotating pivot or alignment post.
