High Tensile 8.8 Grade Hexagonal Head UNF Full Thread Bolt, BS 18.2.1 (1965)

High Tensile 8.8 Grade Hexagonal Head UNF Full Thread Bolt (Compliant with BS 18.2 Part 1 (1965))

The High Tensile 8.8 Grade Hexagonal Head UNF Full Thread Bolt is designed for applications demanding high strength and precision. This bolt features a Uniform National Fine (UNF) thread pattern for fine-tuned tensioning and a full thread length for versatile use in through bolting or where engagement with a nut along the entirety of the bolt’s shaft is necessary. Engineered to meet the British Standard BS 18.2 Part 1 (1965), it represents the industry standard for rounded hexagonal bolts for general purposes.

Key Attributes:

• High Tensile 8.8 Grade Steel: Ensuring robustness and resilience against heavy loads and stress with a tensile strength that classifies it for demanding structural applications.
• Hexagonal Head Configuration: Provides a large surface area for wrenching, allowing for secure fastening and the application of substantial torque without risking tool or head damage.
• Uniform National Fine (UNF) Thread: Delivers a finer thread for better tension control and is often selected for high-precision assemblies where finely adjustable loading and fitting are required.
• Full Thread Coverage: Offers maximum thread engagement for through bolting, ensuring uniform distribution of the load and adaptability to varied thread engagement conditions.
• Standard Compliance: Adheres to the strict definitions set out by BS 18.2 Part 1 (1965), reflecting this bolt’s compatibility and standardization in terms of dimension, strength, and threading for dependable usage in critical fastening.

Applicability:

The full-thread design of this bolt makes it suitable for a wide range of uses in the automotive, aerospace, and general machinery industries, particularly in applications where high tensile fastening is fundamental.

Installation Guidance:

• Match with appropriate UNF nuts that are either the same grade or higher to ensure even strength distribution across the joint.
• Be certain not to exceed the recommended tightening torque to maintain the integrity of the bolt.
• Tools used for installation should fit snugly to avoid rounding off the bolt’s head edges, which can compromise torque application.

Care Instructions:

• Inspect for signs of wear, corrosion, or thread damage at regular intervals, especially if used in harsh environments.
• Consider using thread-locking compounds or similar measures for applications subjected to vibration to prevent loosening over time.

The High Tensile 8.8 Grade Hexagonal Head UNF Full Thread Bolt is a solid choice for versatile binding, offering both the fortitude required for structural stability and the precision necessary for fine adjustments, suitably meeting the long-established BS 18.2 Part 1 (1965) standard.
