CSK SCREW
The CSK screw is a countersunk head fastener manufactured from brass CW614N/CW617N (CuZn39Pb3), designed for applications requiring corrosion resistance and electrical conductivity. The screw features a 90-degree countersunk head with a flat bearing surface and a sharp pointed tip for self-penetration. Thread profiles follow ISO 68-1 standards with a pitch tolerance of ±0.05 mm for sizes M2 to M8.
Brass CW614N is a leaded free-machining alloy with 39% zinc and 3% lead, offering excellent machinability and low friction. The material meets EN 12164 and ASTM B124 specifications for brass fasteners. Typical surface finish is natural brass with no plating, though passivation is available on request. The screws are not heat-treated and retain the ductility of the base alloy, making them suitable for soft materials like wood and plastic.
These screws are commonly used in marine hardware, electrical enclosures, decorative fittings, and woodworking where rust-free fastening is critical. Buyers include hardware distributors, OEM manufacturers in the marine and electronics sectors, and architectural finishers. Packaging is bulk in polybags or cartons of 500 to 5,000 pieces. MOQ and lead time are not specified in the source and must be confirmed directly with the supplier.

Sourcing CSK SCREW from Super Engineers - India Import Guide
Before ordering, confirm the material grade is CW614N or CW617N and request a material test report (MTR) for each batch. Verify the lead content and corrosion resistance against your application’s environmental conditions. Do not assume compliance with international standards without documentation. Request samples for fit and function testing in your target material.
Confirm the packaging method - bulk polybags, cartons, or palletized - along with the quantity per unit. Lead time is not stated but typically ranges from 2 to 6 weeks from India. Payment terms are commonly T/T or L/C. Request Incoterms in writing. Always require a commercial invoice with HS code 7318.15 for customs clearance.
Conduct a pre-shipment inspection for thread quality, head uniformity, and surface defects. Use a thread gauge to verify pitch and diameter. Test a sample batch for torque-to-tension performance. Retain a sample from each shipment for quality control and warranty claims. Ensure the supplier provides a packing list with batch numbers and material certifications.
