Stainless Steel Cylindrical Connector with Threaded Cross Holes

Product overview

The stainless steel cylindrical connector is a cylindrical sleeve part precision machined from 304/316 stainless steel, with a brushed (satin) surface. There is a through hole in the center of the product, and internally threaded transverse holes with countersunk holes are processed at both ends. Set screws can be screwed in to firmly lock the shaft, rod or rope penetrating the center to achieve coaxial docking and positioning of the two rods. This product is suitable for mechanical transmission, guardrail handrails, sports equipment, cable structures and various non-standard assembly scenarios. It is a reliable choice for OEM/ODM customized processing.

 

Product features

High-quality stainless steel material: Made of 304/316 stainless steel, it has excellent corrosion resistance and anti-rust properties, and is suitable for indoor and outdoor as well as humid and chemical environments.

Double-ended internally threaded transverse hole design: There is an internally threaded transverse hole at each end with a countersunk hole step. With the set screw, the central penetration piece can be locked on both sides, making the connection firm and not easy to loosen.

Through-center smooth hole: The center through-hole is smooth and threadless, making it easy for shafts, rods or ropes to penetrate directly. The aperture size can be precisely processed according to matching requirements.

Brushed satin appearance: The surface is carefully brushed, with uniform texture, matte and non-reflective, and the overall texture is delicate and has high industrial aesthetics.

Fine processing of chamfering: The ends and openings are chamfered and deburred, without sharp edges, ensuring safe assembly, smooth threading, and no damage to the workpiece.

 

Application areas

It is widely used in mechanical transmission and connection, guardrail handrails and door and window hardware, sports and fitness equipment, cable and clothes drying rack structures, display shelves, pet supplies and various non-standard customized structures. It is used for the coaxial docking, positioning and locking of two rods/shafts. It is suitable for various manufacturing and assembly companies that pursue reliable connections and fine appearance.

 

Instructions for use

1. Selection confirmation: Select the matching hole diameter specification based on the diameter of the penetrating rod, and confirm that the thread size of the transverse holes at both ends is consistent with the set screw.

2. Cleaning treatment: Before assembly, clean the inner hole of the connector, the surface of the rod and the threaded hole to remove oil stains and iron filings to ensure a clean fit.

3. Penetration and alignment: Insert the rod into the center hole from one end, adjust to the required length, and align the horizontal holes at both ends with the rod to be locked.

4. Locking and tightening: First pre-tighten the set screw on one side, then lock the other side, and finally tighten it gradually in diagonal order to ensure uniform force and centered connection.

5. Check and confirm: After locking, check that the rods at both ends of the connecting piece have no axial movement or skew, and put them into use after confirming they are firm.

 

Maintenance

Regular cleaning: Regularly clean the dust and dirt on the surface of the connecting parts and the threaded holes to keep the appearance and threads clean.

Tightening inspection: Check the set screws regularly for connections that have been exposed to long-term load or vibration environments, and tighten them in time if they are loose.

Anti-rust protection: Stainless steel materials do not require special anti-rust in daily life; if used in a highly corrosive environment, it is recommended to wipe it regularly and keep the surface dry.

Replacement treatment: Replace in time when thread wear, sliding teeth or orifice deformation are found to avoid affecting the connection strength.

 

FAQ

Q: Is the center hole a through hole? How thick a rod can be passed through?

A: It is a through hole, smooth and threadless. The hole diameter can be customized according to customer requirements and used with shafts, rods or ropes of different diameters.

 

Q:What are the specifications of the transverse holes at both ends?

A: The transverse hole is an internally threaded hole with a countersunk step. Commonly used metric threads (such as M4/M5/M6, etc.) are used to install set screws. The specific specifications can be customized according to the drawing.

 

Q: How many set screws does a connector have?

A: There is a transverse hole at each end. Usually, a set screw is provided at each end to lock the center piece. If more reliable double-point locking is required, the double-hole structure can also be processed according to the drawing.

 

Q:What materials and surface treatments can be used?

A: The conventional brushed surface is 304/316 stainless steel. Carbon steel, aluminum alloy, copper and other materials can also be used, and surface treatments such as blackening, galvanizing and polishing can be carried out as needed.

 

Q: What is the minimum order quantity and delivery time?

A: Regular specifications support lower minimum order quantities. The delivery time for batch orders depends on the specifications and quantity. Please contact the business for confirmation for details.
