Stainless Steel Semi-Tubular Rivets that are 3/8″ long RVT-118

$6

Steel, Stainless Steel, and Aluminum

Aluminum semi-tubular rivets have these dimensions:
1/8″ in diameter, 7/32″ head diameter, 3/8″ long shaft (from under the head to the end of the tube), 1/8″ hollow length inside tube

Takes about 1/8″ to set one of these with your setting tool, so these rivets are useful for joining
stuff that ends up with a total thickness of 1/4″ (14 to 16 oz of total leather thickness).
This style of rivet is most often set in a hand or machine press.
