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

Made to order metric socket shoulder screws are precision-engineered fasteners designed for applications requiring exact alignment and consistent spacing. Unlike our off the shelf shoulder screws, these shoulder screws are custom manufactured once you order allowing for 1mm increments in shoulder length.

This level of customisation makes them ideal for high-accuracy engineering projects where tolerances are critical. Typically used in micro machinery, tooling and precision assemblies, these components provide both structural support and precise component spacing.

How Made To Order Metric Socket Shoulder Screws Work

These screws feature an unthreaded shoulder section between the head and the threaded shaft. The shoulder acts as a dowel or shaft, allowing moving parts to rotate or slide with minimal friction. Because they are made to order, each screw is tailored to your exact requirements, ensuring optimal fit and performance.

Although production requires a short lead time of around one week, this brief wait enables unparalleled accuracy and quality, helping engineers avoid compromise and reduce the need for later modifications.

Materials Made To Order Metric Socket Shoulder Screws Are Made From

Accu’s selection of made to order metric socket shoulder screws are available in three key materials.

Stainless steel (A1) offering reliable corrosion resistance and best suited for general-purpose engineering use. For more demanding environments, stainless steel (A4) provides marine-grade protection against corrosion, making it ideal for outdoor or harsh conditions.

Steel variants deliver high mechanical strength, making them suitable for load-bearing applications where corrosion is not a primary concern.

All material variants also offer a choice of raw material finish or black oxide coating.

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

These shoulder screws can be produced to a wide range of specifications. Thread sizes range from M1.6 (1.6mm) up to M24 (24mm), while shoulder diameters span from 2mm to 24mm.

The shoulder lengths are fully customisable in precise 1mm increments, from 2mm to 150mm, allowing for fine-tuned adjustments to meet the exact needs of specialised assemblies.

FAQs

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

A: Approximately one week. This short turnaround allows for exact customisation without compromising on quality.

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

A: Yes, while this category is extermely thorough in its offering, we still offer fully custom made shoulder screws through our screw builder tool.

Q: What applications are these shoulder screws suitable for?

A: They are ideal for precision assemblies in sectors such as aerospace, robotics and instrumentation. They allow for a swivelling mounting point for bearings and other assembly mechanisms.
