Comprehensive Guide to 200mm Hex Bolts Applications and Material Selection
Understanding 200mm Hex Bolts: A Comprehensive Guide
When sourcing fasteners for critical applications, understanding the specifics of each bolt type is paramount. 200mm hex bolts, also known as hexagonal head bolts, are a common choice due to their strength, versatility, and ease of installation. This article will delve into the features, applications, material options, and important considerations when choosing 200mm hex bolts, helping you make informed decisions for your projects. We’ll explore why Gardepota is a trusted source for high-quality hex bolts.
What are 200mm Hex Bolts?
A 200mm hex bolt is a fastener characterized by its 6-sided (hexagonal) head and a length of 200 millimeters (approximately 7.87 inches). The hexagonal head allows for greater torque application using a standard wrench or socket, making them efficient for tightening and loosening. These bolts are typically fully threaded or partially threaded, depending on the specific application requirements. Their robust design makes them suitable for a wide range of heavy-duty applications where a strong and reliable connection is crucial. Gardepota offers a comprehensive selection of these bolts to meet diverse needs.

Common Materials for 200mm Hex Bolts
The material of a 200mm hex bolt is a critical factor determining its performance and suitability for a specific environment. Common materials include:
- Carbon Steel: The most common and cost-effective option, offering good strength and durability. Often used with zinc plating for corrosion resistance.
- Alloy Steel: Provides higher strength and toughness compared to carbon steel. Ideal for demanding applications.
- Stainless Steel: Offers excellent corrosion resistance, making it suitable for outdoor or corrosive environments. Grades 304 and 316 are frequently used.
- High-Strength Steel: Designed for applications requiring extremely high tensile strength.
Material Selection Guide:
• Carbon Steel: General purpose, cost-effective.
• Alloy Steel: High strength, demanding applications.
• Stainless Steel: Corrosion resistance, outdoor use.

Frequently Asked Questions (FAQs)
What is the typical tensile strength of a 200mm hex bolt?
The tensile strength of a 200mm hex bolt varies depending on the material and grade. For example, a Grade 8.8 carbon steel bolt typically has a tensile strength of around 800 MPa, while a Grade 10.9 bolt can reach 1000 MPa. Stainless steel bolts also have varying tensile strengths depending on the specific alloy. It’s crucial to refer to the bolt’s specifications to determine its exact tensile strength for your application. Gardepota provides detailed specifications for all our bolts.
How do I determine the correct length of a hex bolt?
When determining the correct length, consider the thickness of the materials being joined, the desired amount of thread engagement, and any washers or spacers used. As a general rule, the bolt should extend through the materials being fastened, leaving enough thread protruding to accommodate a nut. It's best to measure accurately and allow for slight adjustment. Gardepota offers guidance on bolt length selection based on your specific requirements.
What is the difference between fully threaded and partially threaded 200mm hex bolts?
Fully threaded bolts have threads along their entire length, while partially threaded bolts have threads only on a portion of the shank. Fully threaded bolts are suitable for applications where a consistent clamping force is needed along the entire length of the bolt, such as when fastening thin materials. Partially threaded bolts are typically used for heavier applications where the unthreaded portion of the shank acts as a shear area.
What finishes are available for 200mm hex bolts?
Common finishes include zinc plating (for corrosion resistance), black oxide (for mild corrosion resistance and a black appearance), and hot-dip galvanizing (for superior corrosion protection). Stainless steel bolts typically don’t require additional finishing, as the material itself provides excellent corrosion resistance. Gardepota offers a variety of finishes to suit different environmental conditions.
