EN 3037:1996 - Aerospace series - Screws, pan head, offset cruciform recess, close tolerance normal shank, short thread, in titanium alloy, anodized, MoS2 lubricated - Classification: 1 100 MPa (at ambient temperature)/315 °C

Overview

EN 3037:1996 (adopted as SIST EN 3037:2001) is a CEN aerospace standard that specifies the characteristics of a specific class of fasteners: pan head screws with offset cruciform recess, close-tolerance normal shank, and short thread, manufactured from titanium alloy, anodized, and MoS2 lubricated. The standard defines this product class for applications requiring a high tensile classification: 1 100 MPa at ambient temperature / 315 °C. ICS classification: 49.030.20 (Bolts, screws, studs).

Key topics and requirements

  • Product scope: pan head screws with an offset cruciform (recess) drive, close tolerance normal shank, short thread configuration.
  • Material: specified titanium alloy fasteners - chosen for strength-to-weight ratio and corrosion resistance.
  • Surface treatment: anodized finish to enhance corrosion protection and surface characteristics.
  • Lubrication: MoS2 (molybdenum disulfide) lubrication specified to control friction and achieve consistent torque-tension performance.
  • Strength classification: tensile/strength class defined as 1 100 MPa (ambient) with performance characterized at 315 °C, indicating suitability for higher-temperature service.
  • Conformance: the standard prescribes the characteristics (geometric, material, surface, lubrication, classification) that manufacturers, purchasers and inspection bodies use to verify conformity; it does not provide detailed dimensions in the extract.

Applications

  • Aerospace assemblies where high-strength, lightweight fasteners are required (airframe structural joints, equipment mounting, engine accessory fittings where temperature resilience is needed).
  • Environments demanding corrosion resistance and controlled friction for precise torque-tension relationships (anodized titanium with MoS2).
  • Use by:
    • Aerospace engineers specifying fasteners in design and bills of materials.
    • Fastener manufacturers producing titanium pan-head screws to standard classification.
    • Procurement and quality assurance teams verifying supplier compliance.
    • Maintenance and repair organizations selecting replacement hardware to match original equipment specifications.

Related standards

  • Other CEN/EN aerospace fastener standards covering different head forms, drive types, materials, surface treatments, and strength classes.
  • Industry standards addressing fastener testing, torque-tension relationships, and material specifications (refer to relevant national/adopted standards and OEM requirements).

This standard is essential for consistent specification, manufacture and procurement of titanium aerospace screws with anodized finish and MoS2 lubrication, particularly where a 1100 MPa / 315 °C classification is required. Keywords: EN 3037, aerospace screws, titanium alloy screws, anodized fasteners, MoS2 lubrication, pan head offset cruciform, high-strength fasteners.
