Overview

The Zenith blind rivets are made from quality alloys, and are batch tested by Zenith Aircraft Company for shear strength before being shipped.

These rivets are corrosion resistant, and the stem becomes locked in after being set. Also, not many different lengths are required for different diameters or thicknesses. In the Assembly Instructions, they are designated as A4 (1/8) and A5 (5/32).

They have a design shear strength of 130 lbs. and 220 lbs. respectively. Use only Zenith rivets supplied with the kit.

Zenith Aircraft Company has developed a unique process for setting blind rivets, which requires custom rivet heads. The process uses flush-type rivets, where the flush rivet head is formed into a domed-head by the riveting process. This provides an permanent tight finish to all set rivets. To accomplish this, the riveter heads must be ground (machined) with a concave dome (see diagram). Only 1/8" (A4) and 5/32" (A5) rivets are required to assemble the kit.

Zenair blind rivets for the ZENAIR Riveting System
ZENAIR blind (or pulled) rivets have been used to construct the all-metal Chris Heintz designs since the 1970s, and make riveting a quick and easy process! The ZENAIR riveting system forms the rivet head as the blind rivet is pulled, providing a low profile dome finish and high shear strength. Fast installation, simple tools and low cost make this a popular riveting system with homebuilders!
