S-90269A414 M27 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure.
• Precise component alignment and location thanks to the 60mm shoulder length with a tightly controlled diameter tolerance.
• High mechanical strength and durability with a 70,000 psi tensile strength and Rockwell B79 hardness for demanding applications.
• Secure, non-slip fastening enabled by the 45mm knurled socket head, providing a positive grip for installation and removal.
• Reliable thread engagement ensured by the M27x3mm Class 5g6g thread fit, offering consistent performance and interchangeability.
• Streamlined assembly with a standard hex drive (14mm), allowing for efficient installation with common tools.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring responsible and safe material usage.

Professional Applications & Engineering Value

This M27x3mm shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial machinery. The 316 Stainless Steel material provides exceptional resistance to corrosion from chemicals, saltwater, and high-humidity environments, significantly extending service life in applications like food processing, marine equipment, and chemical plants. The precision-machined 30mm shoulder diameter acts as a secure bearing surface or pivot, eliminating the need for separate spacers and reducing assembly complexity. Combined with the Class 5g6g thread fit, this screw ensures accurate location and smooth rotational movement in linkages, assemblies, and rotating fixtures, preventing misalignment and reducing wear for long-term operational reliability.

Specification Summary & Compliance

This precision shoulder screw features an M27x3mm coarse Metric thread with a Class 5g6g tolerance for a secure fit. The shoulder diameter is held to a tolerance of -0.072 to -0.01 mm, and the shoulder length to 0 to +0.25 mm, ensuring high dimensional accuracy. It is manufactured to provide a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi. This product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
