SS 304/316 CSK Machine Screws for Machinery, Marine Hardware and Equipment Procurement
Start with the installation requirement
If your assembly needs a flush screw head in stainless steel, specify SS 304/316 CSK machine screws rather than a pan head or hex head fastener. The countersunk head is intended to sit into a matching countersink, making it suitable for machinery, marine hardware, equipment and architectural assemblies where head projection must be controlled.
At JLHY, we help you define the screw by application first: mating material, material thickness, installation tool, exposure environment, and the required clamping or sealing function. These details decide whether the order should use 304 or 316 stainless steel, which drive style is practical, and what dimensional standard or buyer drawing should control production.
Specification points to confirm before RFQ
For a clear quotation, you should define the complete screw configuration instead of requesting only a general stainless steel countersunk screw. Our available specification range covers the following product facts:
- Material: Stainless Steel 304 or 316
- Head type: Countersunk/CSK Head
- Drive options: Phillips, Slotted, Torx, Hex Socket
- Thread type: Machine Thread
- Standards: DIN 965, ISO 7046, ANSI or custom requirements
- Diameter range: M2-M12
- Length range: 4mm-100mm
- Finish options: Plain, passivated, polished
- Packing: Box, carton, OEM label
Stainless Steel 304 or 316 should be selected according to the application environment and buyer specification. We do not treat the material grade, dimensional standard or finish as interchangeable; they should be stated clearly on the purchase specification.
Application fit for industrial buyers
SS 304/316 CSK machine screws are used in machinery, marine hardware, equipment and architecture. In these applications, procurement teams often need consistency across head geometry, recess fit, machine thread dimensions and finish appearance.
When you are comparing suppliers, the useful sourcing decision is not only the nominal diameter and length. You also need to confirm the installation tool, the mating component, the required countersink condition, and whether the screw must follow DIN 965, ISO 7046, ANSI, or a custom drawing. We can review the order against the stated standard or approved buyer drawing before production details are confirmed.
Custom production and packing review
We support custom dimensions, head or recess details, thread and point configuration, surface treatment, color, washer assembly and packing requirements where feasible. Final feasibility, tooling, MOQ and lead time are confirmed after technical review, so complete drawings or samples help reduce assumptions at the quotation stage.
For distributors, hardware brands and industrial supply channels, packing can be reviewed as box, carton or OEM label. Please provide pack count, label requirements, artwork if applicable, and destination market requirements with the RFQ.
Information we need for quotation
- Drawing, standard number or physical sample
- Diameter, length, thread, head, drive and point
- Material grade: Stainless Steel 304 or 316
- Finish: Plain, passivated or polished
- Application, mating materials and any test requirements
- Order quantity, packing method, label details and destination market
A complete RFQ allows us to check the technical fit and quote against the same requirement you will use for purchasing, inspection and receiving.
Standards and order-specific quality requirements
We can produce SS 304/316 CSK machine screws to applicable ISO, DIN, JIS, GB or ANSI dimensional requirements, or to an approved buyer drawing. The applicable standard, tolerances, material grade, finish and inspection method should be stated on the purchase specification.
Standards compliance is product- and order-specific. We will not assume a certification, test result or performance level unless it is part of the confirmed order requirement.
