SIST EN ISO 14586:2012 Overview
SIST EN ISO 14586:2012 is an international standard specifying the characteristics of hexalobular socket countersunk head tapping screws. Developed by ISO/TC 2 "Fasteners" and adopted by CEN, this 2011 edition standardizes tapping screws with thread sizes ranging from ST2.9 to ST6.3 inclusive. It supersedes the earlier 2001 edition, ensuring up-to-date specifications for design, dimensions, material, mechanical properties, and tolerances of these specialized fasteners.
The hexalobular socket design, also known as the Torx drive, improves torque transfer and reduces cam-out compared to traditional screw drives. Countersunk heads enable a flush finish in assembled components, making these screws ideal for high-quality mechanical and industrial applications.
Key Topics
- Scope: Defines hexalobular socket countersunk head tapping screws from ST2.9 to ST6.3 thread sizes.
- Dimensions: Precise dimensions and tolerances for screw threads, head geometry, and hexalobular sockets are detailed, following ISO 225 for symbols and ISO 7721 for head gauging.
- Materials and Mechanical Properties: Screws made from heat-treated steel per ISO 2702, ensuring high strength and durability.
- Thread Specifications: Threads conform to ISO 1478, ensuring compatibility and performance.
- Surface Coatings: Electroplated coatings follow ISO 4042, while non-electrolytically applied zinc flake coatings adhere to ISO 10683.
- Product Grades: Product grade A tolerance requirements per ISO 4759-1 guarantee consistent quality.
- Inspection: Acceptance inspections are done conforming to ISO 3269 standards.
- Designation Format: Clear product designation system used, for example, "Tapping screw ISO 14586 - ST3.5 × 16 - R" where “R” denotes round end.
Applications
SIST EN ISO 14586:2012 hexalobular socket countersunk head tapping screws serve numerous practical applications:
- Automotive Industry: Used in vehicle assembly for fastening lightweight panels and components with a smooth surface finish.
- Electronics and Electrical Assemblies: Ideal for securing components requiring reliable torque control and minimal cam-out.
- Industrial Machinery: Durable fastening in equipment and machinery where countersunk heads reduce interference and aid assembly aesthetics.
- Construction: Used in fastening thin sheet metals and materials where a flush screw head finish is needed.
- Furniture and Appliance Manufacturing: Enhances product design by allowing concealed fastening with strong hold.
Their hexalobular drive design reduces wear on tools and improves fastening efficiency, contributing to cost-effective and reliable assembly processes.
