Quality is a primary aspect that is looked for in hardware devices like fasteners, bolts, and screws to employ secure connections of various assemblies. Their crucial involvement in industries’ operations makes them highly invaluable and expected to be reliable. Many projects using bolts require quality and uncompromised features to create an effective assembly in machinery, automotive, and structures. In most intricate sectors customization of bolts has become a standard for ensuring accuracy of materials and functions. But how do we determine the quality of custom bolts and where can we start to look for it? 

Key Criteria for Evaluating Custom Bolt Manufacturers

Customization of bolts and other fasteners is popular in sectors with high fastening requirements and precise suitability specifications. In finding the right features of bolts, selecting the best custom bolt manufacturer is another step that will impact its success rate. The key criteria for identifying custom bolt manufacturers who provide quality services and products include quality standards and certifications, manufacturing capabilities, material class, customization options, and lastly, lead times and delivery.

Quality Standards and Certifications

Standards and certifications of bolts and fasteners have varying guidelines and requirements depending on the aspect of manufacturing, quality management systems, materials, dimensions, threads, surface coatings, and or head markings. Hundreds of standards are implemented in custom bolt manufacturing for different purposes and the multitude of their application. It is important to look for a manufacturer who is accredited or certified with such standards because it serves as a guiding tool for its quality.

• ISO Certifications – ISO or International Standard Organization is globally acknowledged for manufacturing different components. In the fastener industry, this standard is largely implemented to support the consistency of manufactured materials. The most common standard for bolts, screws, and studs made of carbon steel and alloy steel is ISO 898-1. This specifies the requirements for 10 property classes which are equivalent to a grade in “inch” terminology. Bolts under this standard are evaluated at ambient temperature range which should specify their mechanical and physical properties at elevated or lower temperatures.
• Industry-specific Standards – manufacturing standards for specific industries of automotive, aerospace, and marine applications state certain features that suit their environmental conditions. This is extremely important to overcome the challenges and prevent corrosion in materials which leads to fastener failure and accidents.

Manufacturing Capabilities

The manufacturing process of custom bolts includes various steps in cutting, turning, milling, drilling, threading, surface grinding, finishing, laser cutting, forming, wire forming, stamping, and others. Each process involves several pieces of machinery and equipment that can precisely create the desired character of bolts for its end form.

• Equipment and Technology – Advanced equipment and technology have been long introduced in the fastener industry to improve the accuracy and precision of fasteners. Thus, the importance of opting for a manufacturer with the capabilities to provide the right equipment and technology for your custom bolt needs will impact their results and effectiveness.
• Production Capacity – custom bolts can be a time-consuming order from the start of determining their design and features up to the testing processes. But a good bolt manufacturer will provide lead time in achieving deadlines or quick response to requests and lastly to its shipment and delivery.

Material Quality and Sourcing

Raw materials like alloy, steel, aluminum, ferritic stainless steel, etc. can be manufactured by the same company or outsourced from another. Either way, their quality should be checked beforehand to ensure the caliber of the overall material of custom bolts. 

• Types of Materials Used – Fastener materials have a wide range of categories, including metals, plastic, composite materials, and sometimes wood. Depending on the suitable elements of their applications and the right configuration according to their needs, the types of materials used for custom bolts are essential factors to consider with your manufacturer. 
• Sourcing Practices – checking the source of materials in custom bolt manufacturers will determine the class of their priority and principles. Manufacturers should be able to guarantee the quality of their materials by providing clear information about the source.

Customization Options

Customization of bolts has been identified with a comprehensive category in type, size, shape, design, tensile strength, torque, durability, material, and more. 

• Design Flexibility – custom bolts have more flexibility in following specific designs from their application needs. Bolt manufacturers should be able to create versatility for your needs for the best outcome of the final products.
• Prototyping and Testing – the initial prototype and designing of custom bolts is another service for manufacturers with this capability. In this step, customers must communicate their project needs with the company’s engineer and skilled workers to expedite the process. Testing of materials and custom bolts is also inevitable before and after its production, this is to ensure that the product has accurate features according to its purpose and design.

Lead Times and Delivery

Delivery of products is essential to meeting project deadlines and inventory, thus knowing the capacity of your custom bolt manufacturer in asserting your demands will lead to more trust in the process.

• Production Lead Times – the production of custom bolts refers to 3 stages in manufacturing order lead time: pre-production time, production time, and post-production time.  The overall operation will depend on the other capacity of the company such as the process, equipment, machinery capacity in quantity, and others.
• Shipping and Logistics –  custom bolt manufacturers with experience in shipments and exports are preferable for industries in different countries. Since the process may involve uncertainty in days due to uncontrolled situations (i.e. weather problems, docking issues) customers are expected to have adjustments in the expectancy of delivery. However, with the one company with multiple experiences in the field, this has been a consideration from the start which will be estimated accordingly at most times. Another factor that is an advantage for custom bolt manufacturers with experience is their accurate computation of the fees that come along with shipping and logistics. Giving the customers a flexible expectancy and good estimate of the charges.

Evaluating Manufacturer Reputation
