Product Introduction

Non-Standard Products with Head Spraying surface treatment are custom-engineered fasteners designed to meet specific application requirements where standard catalog items do not suffice. These products are manufactured according to customer-provided drawings or samples, enabling precise dimensional and performance characteristics for specialized applications. The head spraying surface treatment provides a protective coating applied directly to the fastener head, offering corrosion resistance, enhanced appearance, and improved wear protection. Available in carbon steel (C1022A) and stainless steel (SUS410, SUS304, SUS316) material options, these non-standard fasteners offer strength and corrosion resistance for various environments. Multiple head configurations including countersunk, semi-countersunk, flared, disk, round washer, flat round head, and non-standard head shapes accommodate diverse application requirements. Various drive options and surface treatments provide comprehensive customization capabilities for unique fastening needs.

Common Questions and Solutions

How do I place an order for non-standard products?

Submit detailed drawings or provide physical samples for customization. Include specifications such as material, grade, dimensions, head type, drive type, thread specification, surface treatment, and any special requirements.

What is head spraying surface treatment?

Head spraying is a surface treatment process where a protective coating is applied directly to the fastener head. This provides corrosion resistance, enhanced appearance, improved wear protection, and can be color-matched for aesthetic applications.

What material options are available for non-standard products?

Material options include carbon steel (C1022A) for general applications, and stainless steel grades SUS410 for hardness, SUS304 for general corrosion resistance, and SUS316 for marine-grade protection.

What is the minimum order quantity for non-standard products?

Minimum order quantity varies based on product complexity, material selection, and manufacturing requirements. Contact our sales team for specific MOQ information for your custom application.

Can you match specific color requirements for head spraying?

Yes. Head spraying can be color-matched to specific requirements. Provide color specifications such as RAL, Pantone, or custom color codes for accurate matching.

What is the typical lead time for non-standard products?

Lead time varies based on product complexity, quantity, and current production schedule. Contact our sales team for specific lead time information based on your customization requirements.

Customization Considerations

Provide detailed drawings or physical samples with complete specifications including dimensions, tolerances, material, and surface treatment requirements.

Specify the required head type and drive configuration based on installation tool availability and torque requirements.

Select the appropriate material grade based on strength and corrosion resistance requirements for the application environment.

Specify head spraying color and finish requirements for aesthetic and protective purposes.

Confirm quantity requirements and delivery timeline for production scheduling.

Review and approve pre-production samples before full production begins.
