Overview
EN 14219:2003 is a harmonized European standard developed by CEN for hexagon bolts with flange, featuring metric fine pitch thread in a small series format. These bolts are intended for mechanical assemblies demanding high precision, robust clamping, and superior performance, shortlisting nominal thread diameters from 8 mm to 16 mm. The standard covers bolts made of both steel and stainless steel-with property classes 8.8, 9.8, 10.9, 12.9, and A2-70-and specifies product grade A for quality assurance.
EN 14219:2003 is based on ISO 15072:1999, with key modifications for European applications. It focuses on dimensional characteristics, mechanical properties, tolerance grades, and coating options, underpinning reliable use in engineering, automotive, and industrial sectors.
Key Topics
- Scope of Products: Defines hexagon bolts with flanged heads and fine metric threads in the size range of 8 mm to 16 mm for grades 8.8, 9.8, 10.9, 12.9, and stainless class A2-70.
- Design Specifications: Details the dimensional requirements-width across flats, head heights, flange dimensions, and thread characteristics.
- Material and Property Classes: Includes both carbon/alloy steel and stainless steel bolts, referencing appropriate classes for mechanical strength and corrosion resistance.
- Surface Finishes:
- As processed
- Black oxide (thermal or chemical)
- Electroplating as per EN ISO 4042 (for varied protective coatings)
- Zinc flake coatings under EN ISO 10683
- Tolerances and Product Grade: Adopts tolerance class 6g (threads) and product grade A, conforming to EN ISO 4759-1.
- Inspection and Compliance: Outlines inspection guidelines, acceptance criteria, and gauging practices, referring to EN ISO 3269 for acceptability.
- Designation System: Provides unambiguous product identification for ordering and traceability.
Applications
EN 14219:2003 hexagon flange bolts are widely used in:
- Automotive Assembly: Ideal for connecting chassis, engines, and suspension components where fine pitch threading and reliable clamping are critical.
- Machinery and Equipment: Utilized in the construction of industrial machines, robotics, and heavy-duty systems requiring precise fastening solutions.
- Precision Engineering: Suited for assemblies needing controlled preload and minimal loosening, such as instrumentation, pumps, and valves.
- Steel Fabrication: Employed in frameworks and structures where enhanced bearing surface (provided by the flange) reduces risk of component damage.
The fine pitch threads maximize adjustment and retention, while the flange head ensures even load distribution, reducing the need for separate washers and enhancing assembly speed.
