Product Selection Differences for Workholding Contact Bolts

When selecting workholding contact bolts, there are several key differences and considerations to keep in mind. Here are the most important factors to consider:

1. Material:

   • Workholding contact bolts are made from a variety of materials including steel, aluminum, and plastic. Steel bolts offer high strength and durability, while aluminum bolts are lighter and resistant to corrosion. Plastic bolts may be used for specific applications where non-marring surfaces are required.

2. Size and Thread Type:

   • Consider the diameter, length, and thread type (e.g., coarse or fine) of the bolts. These specifications should match both the workpiece and the fixture they are being attached to. Incompatible sizes can lead to ineffective clamping and damage.

3. Load Capacity:

   • Different bolts are rated for different load capacities. Ensure that the contact bolts you choose can handle the maximum load you expect to apply during machining or holding operations.

4. Design and Geometry:

   • The design of the bolt (e.g., hex head, flat head, etc.) can impact how easily it can be tightened or adjusted. Features like a tapered or rounded body can affect the contact surface and the ability to hold the workpiece securely without marring.

5. Surface Finish:

   • The finish of the bolt can affect friction and wear. For example, a smooth surface may reduce sticking, while a rougher finish may provide better grip. Coatings like zinc plating or black oxide can also improve resistance to corrosion.

6. Compatibility with Workholding Systems:

   • Ensure that the bolts are compatible with the specific workholding system being used, whether it's a vise, fixture, or another mechanism. Some systems may require specific bolt styles or designs.

7. Speed of Setup:

   • Consider how quickly and easily the bolts can be installed and removed. Features like quick-release mechanisms or thumb screws can enhance efficiency, especially in environments with frequent setup changes.

8. Temperature and Environmental Resistance:

   • If the workholding application involves extreme temperatures or hazardous environments (e.g., exposure to chemicals), it’s important to choose bolts that can withstand these conditions.

9. Cost and Supplier Support:

   • Different suppliers may offer various pricing based on quality, brand reputation, and after-sales support. Consider not just the upfront cost but also the long-term value, including warranty and customer service.

10. Regulatory Compliance:

    • Ensure that the bolts meet industry standards and regulations, particularly in fields like aerospace or automotive manufacturing, where safety and performance are critical.

11. Customization Options:

    • Some manufacturers offer customizable solutions for specific applications, which could be beneficial if standard options do not meet your particular needs.

By considering these factors, you can select the most appropriate workholding contact bolts for your specific application, ensuring efficient, safe, and effective workholding in your production process.
