SS 304/316 Hex Socket Set Screws for Shafts, Pulleys and Machinery

Deciding the Right Set Screw Specification Before RFQ

For importers, distributors, wholesalers, procurement managers and industrial buyers in India, the first sourcing decision is not only whether the screw is stainless steel. You need to confirm how the screw will hold the mating part, which point style is required, which dimensional standard applies and how the order should be packed for your supply channel.

At JLHY, we supply SS 304/316 set screws for shaft, pulley, collar, gear, knob and machinery applications. Our product scope covers stainless steel 304 or 316 material options, headless set screw construction, hex socket drive, M2-M16 diameters and 3mm-100mm lengths. You can reference our SS 304/316 set screws product page when preparing a quotation request.

Material, Drive and Point Selection

The available material options are stainless steel 304 or 316. Selection should be stated clearly in the purchase specification together with the finish, dimensions and point style. We can review cup point, cone point, flat point and dog point requirements according to the buyer’s application and drawing or standard reference.

• Material: Stainless Steel 304 or 316
• Head type: Headless set screw
• Drive type: Hex socket
• Point types: Cup point, cone point, flat point, dog point
• Finish options: Plain or passivated

The point type affects how the set screw contacts the shaft, collar, gear or other mating component. For quotation accuracy, include the point requirement rather than leaving it to assumption.

Standards, Sizes and Application Fit

We support set screw specifications referencing DIN 916, DIN 913, DIN 914 and DIN 915. Production can also be reviewed against applicable ISO, DIN, JIS, GB or ANSI dimensional requirements, or against an approved buyer drawing. Standards compliance is product- and order-specific, so the applicable standard, tolerances, material grade, finish and inspection method should be included in the RFQ.

• Diameter range: M2-M16
• Length range: 3mm-100mm
• Typical applications: Shaft, pulley, collar, gear, knob and machinery
• Standard references: DIN 916, DIN 913, DIN 914, DIN 915

For technical evaluation, confirm the mating material, installation tool, exposure environment and required clamping or seating function. These details help us review whether the requested headless hex socket set screw configuration matches the intended assembly.

Customization and OEM Packing Review

At JLHY, we can review custom dimensions, head or recess details, thread and point configuration, surface treatment, color, washer assembly and packaging requirements. Final feasibility, tooling, MOQ and lead time are confirmed after technical review, based on the requested specification and order details.

Packing options include box, carton and OEM label. If your order is for distribution, importer stock or brand supply, provide the carton requirement, small-box count, label details and destination market requirements with the RFQ.
