Key features

The ISO 7379 Shoulder Screw combines a precision shoulder section and threaded end in one fastener, providing accurate positioning for rotating, sliding, guiding, and locating assemblies.

The Stainless Steel Shoulder Screw offers good corrosion resistance and a clean surface finish, making it suitable for machinery, fixtures, automation equipment, and precision mechanical systems.

An internal hexagon drive allows efficient torque transmission while keeping the head compact, giving the Hex Socket Shoulder Screw reliable installation performance in space-limited assemblies.

The smooth cylindrical shoulder can function as a bearing surface, guide pin, pivot, or spacer, helping the Precision Shoulder Bolt maintain controlled movement and alignment between connected parts.

Shoulder diameter, shoulder length, thread size, thread length, head dimensions, material, and finish can be customized for Precision Shoulder Screws according to drawings or technical requirements.

It reports TS 16949 and ISO 9001 certifications, more than 10 production lines, 6–10 quality-control staff, and shipment inspection reports with material certificates. The supplier provides 3D software design, ODM, and several customization options, but reports no new products in the past year, no SDK, and no OEM service for popular brands. Service-management documentation is weak: no written procedures or records are reported for assessments, corrective actions, or complaint handling. It has no in-stock capability, overseas warehouse, or overseas showroom. Financial records are indicated for 2023–2025, but their results are not provided, so financial credibility cannot be determined. No customer cases are supplied.

Its stated scope covers fasteners, metal products, machinery, vehicle parts, CNC machining, stamping, casting, die-casting, plastic, and rubber parts, indicating broad manufacturing and industrial-product coverage.

CertificationsThe supplier reports holding TS 16949 and ISO 9001 management-system certifications. It also states that each shipment will include an effective inspection report and corresponding material certificate, providing explicit evidence of documented quality-related controls.

After-Sales capabilityThe supplier reports no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. It also lacks in-stock service, overseas warehouse, and overseas showroom capabilities, indicating a documented weakness in after-sales and service infrastructure.

It is located near Ningbo and Shanghai ports and reports 21 qualified suppliers, but has no inventory capability and peak-season lead-time data is inconsistent or unclear.

Product Q&A

Q:What is an ISO 7379 shoulder screw used for?

An ISO 7379 Shoulder Screw is commonly used as a pivot, guide, locating pin, bearing surface, or spacer in molds, machinery, automation systems, fixtures, and moving mechanical assemblies.

Q:What is the difference between a shoulder screw and a standard bolt?

A Stainless Steel Shoulder Bolt has a precisely defined smooth shoulder section that can support positioning or movement, while a standard bolt is primarily designed for clamping through its threaded shank.

Q:Can the shoulder diameter and length be customized?

Yes. A Precision Shoulder Screw can be manufactured with customized shoulder diameter, shoulder length, thread size, thread length, and head dimensions according to application requirements.

Q:Why is the shoulder section smooth instead of threaded?

The smooth section of a Hex Socket Shoulder Bolt provides a consistent contact surface for rotating, sliding, or locating components and helps reduce interference that a threaded surface could create.

Q:What materials and finishes are available?

The Socket Head Shoulder Screw can be supplied in stainless steel, alloy steel, or carbon steel. Common finishes include stainless steel natural finish, black oxide, zinc plated, nickel plated, and Dacromet.
