Exploring the Advantages and Disadvantages of ... - Bolts | Nuts

In the world of fasteners, hex bolts play a crucial role in various industries. To enhance their performance and protect against corrosion, different surface treatments are applied. Today, we delve into the advantages and disadvantages of five common surface treated hex bolts: Stainless Steel Hex Bolts, Black Oxide Hex Bolts, Zinc Plated Hex Head Bolts, Hot Dip Galvanized Hex Bolts, and Yellow Zinc Bolts.

View Details


Stainless Steel Hex Bolts:

Advantages:

Exceptional corrosion resistance, suitable for marine, chemical, and food processing industries.

High strength and durability, ensuring long-lasting performance.

Aesthetically pleasing, maintaining a polished appearance over time.

Disadvantages:

Relatively higher cost compared to other surface treatments.


Black Oxide Hex Bolts:

Advantages:

Enhanced corrosion and wear resistance, ideal for automotive and electronics industries.

Reduced light reflection, providing an appealing appearance.

Minimal dimensional changes during treatment, maintaining tight tolerances.

Disadvantages:

Less effective in highly corrosive environments compared to other treatments.


Zinc Plated Hex Head Bolts:

Advantages:

Cost-effective option for applications in indoor and mildly humid environments.

Adequate corrosion resistance for general purposes like furniture manufacturing and light construction.

Easy to apply and readily available.

Disadvantages:

Susceptible to corrosion in harsh or outdoor conditions.

Thinner coating compared to other treatments, offering limited protection.


Hot Dip Galvanized Hex Bolts:

Advantages:

Superior corrosion resistance, making them suitable for outdoor and harsh environments.

Long-lasting protection against rust and corrosion, ideal for construction and infrastructure projects.

Relatively low maintenance required.

Disadvantages:

Thick coating may impact dimensional accuracy and thread fit.

Initial cost and processing time may be higher compared to other treatments.


Yellow Zinc Bolts:

Advantages:

Cost-effective choice for applications with low to medium corrosion risks.

Aesthetically appealing, offering an attractive yellow finish.

Suitable for furniture manufacturing, mechanical assembly, and general construction.

Disadvantages:

Moderate corrosion resistance compared to other surface treatments.

Limited suitability for highly corrosive environments.


Choosing the right surface treated hex bolts for a specific industry involves evaluating the project's environmental conditions, budget constraints, and required level of corrosion protection. By understanding the advantages and disadvantages of each treatment, businesses can make informed decisions to ensure the long-term performance and success of their projects.


Advantages And Disadvantages Of Outer Hexagon Bolt And ...

Advantages And Disadvantages Of Outer Hexagon Bolt And Inner Hexagon Screw

Postview: 263       Date:February 14,

When using mechanical equipment, fasteners are necessary if you want them to work properly. However, after looking at many designs, we found that almost all fastener designs use hexagon socket screws, whether countersunk or non-countersunk. Some people may wonder why many mechanical devices use inner hex screws instead of outer hex bolts. What are the advantages of inner hex screws?

As a leading fastener manufacturer in China, Xinchi Fastener Company has many years of experience in the fastener field. Today we are going to discuss with you the advantages and disadvantages of outer hexagon screws and inner hexagon screws.

Outer hexagon bolts

The thread on the outer hexagon bolt is generally fine tooth ordinary thread. External hexagon screws with common thread around the ring teeth have better self-pin performance, mainly used on thin-wall parts or under the impact, vibration, or alternating load.

Generally, external hexagon screws are partially threaded. Full-threaded outer hexagon screws are mainly used for short outer hexagon screws with nominal length and longer thread requirements. External hexagon screws with holes are used when external hexagon screws are needed for locking. External hexagon screws with hinged holes can accurately fix the relative position of the connected parts and can be subjected to shear and extrusion caused by die force.

The advantage of the outer hexagon blots is that the pre-loading contact area is large, and the pre-loading force can be used very much. It is generally used in large equipment, and the price is lower than the inner hexagon. The disadvantage of outer hexagon screws is that they occupy a large space and cannot be used in countersunk holes.

Hexagon socket screws

Hexagon socket screws are often used in machinery, which is easy to tighten, and disassemble, and not easy to slide Angle. An Allen wrench is usually a 90° turn, one end is long and the other is short. When using the short side of the Allen wrench to screw, we can hold the long side, which can save a lot of force and can better tighten the screw. The long end of the inner Allen wrench has a round head (hexagonal cylinder similar to the ball) or a flat head. And the round head can be very convenient for oblique disassembly, used to install some parts that are not convenient to use a wrench.

The manufacturing cost of outer hexagon screws is much lower than that of inner hexagon screws. The outer hexagon screw has the advantage that the screw head (wrench stress position) is thinner than the inner hex screws, and can not be replaced by inner hex screws in some places. In addition, machinery with low cost, small power strength, and low precision requirements use hex screws more frequently.

The advantage of inner hexagon screws is that it occupies a small space and can be used as a countersunk head, which is generally used in small equipment. Its disadvantage is that the preload contact area is small, and can not use too large preload force. In addition, the price of hexagon screws will also be a little more expensive, after a certain length there is no full thread.
