M90-45 Bolt

Updated: 2026-09-12

Overview

The M90-45 Bolt is a standardized mechanical fastener designed for heavy-duty industrial applications. Its designation typically indicates specific dimensional characteristics, with 'M' representing metric thread and the numbers denoting size parameters. As an essential component in machinery assembly and structural applications, this bolt offers reliable fastening solutions where high strength and durability are required. Manufacturers produce M90-45 bolts in various material grades to meet different performance requirements.

Structure and Working Principle

The M90-45 Bolt features a threaded shaft with precise pitch and diameter specifications, designed to mate with corresponding nuts or threaded receptacles. The bolt's working principle relies on creating tension between joined components when properly torqued. Key structural elements include the head (typically hexagonal for wrench application), shank, and threaded portion. The specific dimensions and thread pattern (likely coarse or fine metric thread) determine its compatibility with other fastening components in the assembly.

Key Features

M90-45 Bolts are characterized by their high tensile strength, often meeting or exceeding ISO 898-1 class 8.8 or higher specifications. The bolts may feature various surface treatments such as zinc plating or hot-dip galvanizing for corrosion resistance. Manufacturers can produce these fasteners with different head styles (hex, flange, or socket) to accommodate specific installation requirements. The precise threading ensures secure fastening and vibration resistance in demanding applications.

Application Areas

Primary applications for M90-45 Bolts include heavy machinery assembly, structural steel construction, and industrial equipment manufacturing. These fasteners are commonly used in sectors such as automotive, aerospace, and energy infrastructure. Specific uses may include connecting structural steel members, securing large mechanical components, or fastening pressure vessels. The bolt's size and strength make it suitable for applications where standard fasteners would be inadequate.

Maintenance and Precautions

Proper installation of M90-45 Bolts requires calibrated torque tools to achieve specified clamping force without damaging threads. Periodic inspection for loosening or corrosion is recommended in critical applications. Storage should be in dry conditions to prevent rust formation. When reusing bolts, carefully inspect for thread damage or stretching. Always use matching nuts and washers of equivalent grade to maintain joint integrity.

B2B Procurement Guide

When sourcing M90-45 Bolts, specify material grade, surface treatment, and dimensional tolerances. Bulk purchases typically offer cost advantages, with standard packaging in boxes or drums for industrial quantities. Quality certifications such as ISO 9001 or specific industry standards (e.g., ASTM, DIN) should be verified. Lead times may vary based on material specifications and quantity requirements. Consider supplier capabilities for custom modifications if needed.
