Product Description: High Tensile 8.8 Grade Hexagonal Head Bolt – BSW Thread, Half-Threaded
Specifications:
- Grade: 8.8, high tensile strength, indicative of a medium-carbon steel with good tensile strength and is widely used in industrial applications for its robustness.
- Thread Design: Half-threaded, providing a dual-functionality with the threaded portion securing the bolt and the unthreaded shank offering sheer resistance and alignment features.
- Thread Standard: BSW (British Standard Whitworth), a coarse thread pattern known for its compatibility with a wide range of fastening tasks and particularly common in historic or traditional British applications.
- Head Style: Hexagonal head, the six-sided design allows for a reliable interface with tools, providing ample leverage for high-torque applications.
- Standards Compliance: Fully compliant with BS 18.2.1 (1965), the specific British Standard that sets out the characteristics for this type of bolt, ensuring a high level of consistency and uniformity in product quality.
- Finish: Typically, bolts of such standards come with a protective finish against corrosion, although the specific type of finish is not mentioned. Usually, a zinc-plating or black oxide finish is applied to such bolts.
Intended Applications:
- Construction: For structural elements that require robust bolts and can benefit from the shear resistance provided by the unthreaded shank.
- Heavy Machinery: In the composition of machinery where high-strength fasteners are a must to withstand the mechanical stresses during operation.
- General Industrial Use: Suited for applications across various industries where the strength grade and BSW thread compatibility are necessitated.
- Restoration Projects: Ideal for restoration or maintenance work on equipment and structures that have been originally designed with BSW thread standards.
Usage and Quality Consideration:
Users should match these bolts with compatible BSW-threaded nuts. Bolts should be selected based on correct length, diameter, and thread engagement to ensure the intended mechanical properties are achieved. Quality control measures should confirm thread integrity and tensile strength adherence to BS 18.2.1 (1965) standards. Proper storage to prevent corrosion is also recommended unless a corrosion-resistant coating is verified.
Given the bolt’s 8.8 high tensile grade, consider conducting randomized batch testing to validate the bolt’s material properties to maintain stringent quality assurance standards across your supply
