Socket Head Shoulder Screw With Nylon Patch

Short Description:

This socket head shoulder screw with nylon patch is designed for precise positioning, guided movement, and anti-loosening fastening in mechanical equipment, automation assemblies, fixtures, and industrial hardware structures. It features a cylindrical socket head, smooth shoulder shaft, threaded end, and blue nylon locking patch for stable installation under vibration or repeated operation.

Built For Fastening And Controlled Movement

The socket head shoulder screw with nylon patch is a precision fastening component that combines a strong head structure, smooth shoulder section, and threaded locking end in one part. The socket drive allows controlled tightening with a hex key, while the shoulder shaft provides accurate spacing, guiding, rotation support, or positioning between assembled components.

Compared with ordinary fully threaded screws, shoulder screws are more suitable for assemblies that require both fastening and controlled movement. The smooth shoulder section can work as a locating shaft, support pin, or guide surface, helping maintain alignment and reduce direct thread contact in moving or positioned assemblies.

Structure Breakdown

Socket Head

Supports strong tightening force and convenient installation with a hex key for controlled assembly.

Smooth Shoulder Shaft

Provides accurate positioning, spacing, guiding, or rotation support in precision mechanisms.

Threaded Locking End

Provides secure fastening while the shoulder body performs locating or motion-support functions.

Blue Nylon Patch

Increases thread friction and helps reduce loosening caused by vibration, impact, or repeated use.

Product Appearance

The product features a black socket head, a smooth metallic shoulder body, and a black threaded end with blue nylon patch. This appearance gives the screw a clean industrial look while clearly separating the locating shaft and locking thread areas.

Why The Shoulder Section Matters

The smooth shoulder section helps reduce direct thread contact in moving or positioned assemblies. It can act as a locating shaft, guide pin, support surface, or pivot point, making it suitable for structures that require stable alignment and controlled movement.

Product Features

Socket Head Design: Supports strong tightening force and convenient installation with a hex key.

Smooth Shoulder Shaft: Provides accurate positioning, spacing, guiding, or rotation support.

Blue Nylon Patch: Helps improve anti-loosening performance in vibration-prone assemblies.

Partial Thread Structure: Combines precise shoulder support with secure threaded fastening.

Durable Surface Finish: Black head and threaded section provide a clean industrial appearance.

Custom Manufacturing: Shoulder size, thread length, material, finish, and locking patch can be customized.

Suitable Applications

This shoulder screw is commonly used in precision assemblies where a screw must provide fastening while also serving as a shaft, spacer, guide, or support surface. It is especially suitable for mechanisms that involve positioning, sliding, rotating, or repeated movement.

Automation equipment

Mechanical positioning structures

Fixtures and tooling assemblies

Mold and die components

Sliding or rotating mechanisms

Industrial machinery

Precision hardware assemblies

Custom equipment fastening systems

Custom Shoulder Screw Options

Yuhuang can provide customized shoulder screw solutions according to drawings, samples, or application requirements. Shoulder diameter, shoulder length, thread size, thread length, material, surface treatment, hardness, and nylon patch position can be adjusted to meet different assembly needs.

Compared With Fully Threaded Screws

Ordinary fully threaded screws are mainly used for direct fastening. Shoulder screws add a smooth shaft section, making them more suitable for spacing, guiding, positioning, sliding, or rotating functions.

Added Locking Performance

The blue nylon patch increases thread friction during installation, helping reduce loosening in vibration-prone equipment, moving mechanisms, and repeated-use assemblies.
