PATIKIL M5x40mm Threaded Stud Screw 304 Stainless Steel Hex Bolt

Description

Product Overview

The PATIKIL M5x40mm double‑end threaded stud screw is engineered for demanding applications where reliability and precision are paramount. Crafted from premium 304 stainless steel, each bolt delivers exceptional corrosion resistance, ensuring long‑term performance even in humid or outdoor environments. The screw measures 1.57 inches (40 mm) in total length with a 7 mm hex head, providing a robust interface for standard open‑end wrenches. Its unique design incorporates left‑hand threads on one end and right‑hand threads on the opposite end, each extending 15 mm, enabling simultaneous tightening from both sides. This dual‑thread configuration creates a self‑locking mechanism that minimizes loosening under vibration, making it an ideal choice for furniture assembly, cabinet construction, and a wide range of household maintenance tasks. The package includes ten meticulously finished studs, each inspected for dimensional accuracy and surface integrity, guaranteeing consistent fit and function across all units.

Usage

Designed with versatility in mind, the M5x40mm stud screw excels in both professional and DIY settings. In furniture manufacturing, the opposite threads allow technicians to secure panels and frames quickly, reducing assembly time while maintaining structural rigidity. Homeowners can employ the screws for mounting shelving brackets, securing door hinges, or reinforcing tabletop joints where traditional single‑direction bolts might slip under load. The stainless‑steel construction also makes the fastener suitable for kitchen and bathroom installations, where exposure to moisture and cleaning agents is routine. Because the threads are mirrored, users can select the appropriate end for the specific direction of force required, providing greater control during installation. Whether you are building a custom workbench, repairing a wooden gate, or installing metal brackets for outdoor lighting, the PATIKIL double‑end stud screw delivers dependable performance and ease of use.

FAQ

What is the advantage of having left‑hand and right‑hand threads on the same stud?

The opposite threads enable the fastener to be tightened from either side, creating a self‑locking effect that resists loosening under vibration. This feature is especially useful in applications where access to both ends is limited or where additional security is required.

Can I use these studs with standard nuts?

Yes. The left‑hand thread matches standard left‑hand nuts, and the right‑hand thread matches standard right‑hand nuts. Ensure you select the correct nut orientation to correspond with the thread direction of the stud end you are using.

Are these screws suitable for outdoor projects?

Absolutely. The 304 stainless steel material provides excellent resistance to rust and corrosion, making the studs ideal for outdoor furniture, garden structures, and any environment exposed to moisture.

How do I determine the correct torque setting for installation?

We recommend a torque range of 0.8–1.2 Nm for the M5 size when using a standard hex wrench. Applying torque within this range ensures a secure fit without over‑tightening, which could damage the threads.

What should I do if a nut does not thread properly onto the stud?

First, verify that the nut matches the thread direction of the stud end you are using. If the direction is correct, inspect both the nut and the stud for debris or damage. Clean any foreign material and re‑attempt installation. If issues persist, contact PATIKIL customer support for assistance.
