1000PCS Rivets ljhnba M0.9 M1.3 M1.5 M1.7 Copper Hollow Kit for PCB

Description

Product Overview

The 1000PCS Rivets M0.9 M1.3 M1.5 M1.7 Mix Copper Hollow Kit is engineered for precision electronic assembly and light‑weight mechanical fastening. Each rivet is fabricated from high‑conductivity copper, offering excellent electrical continuity while the hollow shaft reduces material weight and allows for easy insertion. The kit includes a balanced assortment of four standard diameters—M0.9, M1.3, M1.5, and M1.7—providing flexibility for a wide range of printed circuit board (PCB) thicknesses and component layouts. All 1000 pieces are supplied in a compact, resealable pouch that protects the rivets from deformation and contamination, ensuring they remain ready for immediate use. The design follows industry‑standard solid rivet dimensions, making the kit compatible with common grommet tools and press machines, yet it also works well in hand‑tool applications for rapid prototyping.

Usage

These copper hollow rivets excel in environments where reliable electrical grounding and mechanical stability are required simultaneously. Typical applications include securing component leads on multi‑layer PCBs, attaching heat‑sink brackets, mounting lightweight metal brackets inside enclosures, and reinforcing cable ties in aerospace or automotive prototypes. To install, drill a hole slightly larger than the rivet’s outer diameter, insert the rivet, and then use a standard press or a simple hand‑tool to expand the shaft, creating a secure, vibration‑resistant joint. For solder‑based assemblies, the rivet can be positioned, then soldered on the opposite side to lock it in place, providing both mechanical and electrical bonding. The kit’s range of sizes allows engineers to select the optimal diameter for each board thickness, minimizing excess material while maintaining structural integrity.

FAQ

Can these rivets be used on non‑copper surfaces?

Yes, the copper hollow rivets can be installed on a variety of substrates, including aluminum, steel, and composite materials. While copper offers superior electrical conductivity, the mechanical design of the rivet—its hollow shaft and flanged head—provides a secure hold on non‑conductive surfaces as well. For best results on dissimilar metals, it is recommended to use an appropriate anti‑galvanic barrier or coating to prevent potential corrosion.

What is the recommended hole size for each rivet diameter?

The optimal hole diameter is typically 0.1 mm larger than the outer diameter of the rivet. For example, an M0.9 rivet (0.9 mm diameter) should be installed in a hole of approximately 1.0 mm, while an M1.7 rivet works best with a 1.8 mm hole. This slight oversize allows the rivet to be inserted easily and then expanded securely during the pressing or soldering step.

Do I need a special tool to expand the hollow shaft?

No special tool is required beyond a standard solid‑rivet press or a simple hand‑tool that can apply axial force. The hollow shaft is designed to expand uniformly when pressure is applied, creating a tight fit in the drilled hole. For high‑volume production, a pneumatic press can speed up the process, but many hobbyists and small‑scale manufacturers successfully use a manual rivet gun.

How should I store the rivets to maintain their quality?

Store the rivets in a cool, dry environment away from direct sunlight and moisture. The resealable pouch included with the kit protects the pieces from oxidation and physical deformation. For long‑term storage, consider placing a desiccant packet inside the pouch to absorb any residual humidity, ensuring the copper remains clean and ready for immediate use.
