Mate rivets are interlocking, two-piece fasteners designed for applications where access to both sides of the workpiece is available but precision hole tolerances are not required. This system consists of a tubular component and a mating rivet that engage from opposite sides of the material. Once set, the male rivet expands inside the female tubular component, creating a strong, permanent joint without crushing or distorting the parent material. Their exceptionally wide grip range—reaching thicknesses up to 3-7/8 inches—makes mate rivets suitable for assemblies requiring extra-long fasteners.
Understanding Mate Rivets
A mate rivet assembly includes two parts: • A tubular female component inserted from one side • A solid male rivet inserted from the opposite side
During installation, the rivet expands inside the tubular sleeve, locking both components together. Because no precise hole sizing is required, mate rivets are ideal for joining thick or uneven materials. The design produces a secure, vibration-resistant joint that cannot be easily removed, making it a reliable option for both structural and security-focused applications.

Advantages of Mate Rivets
Easy Installation
Installed with a standard blind rivet tool—no specialized equipment or tight-tolerance holes required.
Permanence
Designed to form a permanent fastening solution, ideal for applications that require tamper resistance.
Vibration-Resistant Joint
The interlocking design provides excellent resistance to loosening in environments with continuous movement or vibration.
Extremely Wide Grip Range
Can fasten material stacks up to 3-7/8 inches thick, making them suitable for oversized or multi-layered assemblies.
Versatile Use
Common in automotive interiors, furniture manufacturing, consumer goods, maintenance applications, and other industries requiring long or flexible fasteners.
Installation Process
Align the Components
Position the materials to be joined, ensuring the holes line up properly.
Insert the Male Component
Insert the male rivet through the hole from one side of the assembly.
Engage the Female Component
Align the tubular female sleeve on the opposite side, then set the rivet using a standard blind rivet setting tool. The male rivet expands inside the sleeve, locking the assembly securely.
