Product Description
Steel Dome Head Structural Blind Rivets – 4.8mm and 6.4mm
These steel dome head structural blind rivets provide strong permanent fixings for assemblies where access is available from one side only. Available in 4.8mm and 6.4mm diameters, they feature a zinc plated steel body and stem, a multi grip design and a mechanically locked stem.
During installation, the rivet body forms against the rear of the joint, drawing the materials together. The retained stem locks into the body to help create a strong, vibration-resistant connection.
Key Features
- Structural design: high shear and tensile strength for demanding fastening applications.
- Steel body and stem: both zinc plated for added corrosion protection.
- Mechanically locked stem: retains the stem within the installed rivet.
- Multi grip capability: accommodates a range of material thicknesses within each rivet's specified grip range.
- Single-sided installation: suitable where the rear of the joint is inaccessible.
- Dome head: provides a raised bearing surface on the accessible side.
- Gap-closing capability: helps draw the components together during setting.

Sizes are given as rivet body diameter x body length. Body length is not the same as grip range.
Typical Applications
- Sheet metal fabrication and enclosure assembly.
- Vehicle bodywork and panel assemblies.
- Equipment housings, brackets and general manufacturing.
- Permanent joints requiring structural blind fasteners.
Choosing the Correct Rivet
Measure the combined thickness of all materials being joined and choose a rivet with a suitable grip range. Check that the hole diameter and rivet strength meet the requirements of your assembly.
Installation Advice
Use a riveting tool with sufficient pulling capacity and the correct nose equipment for the selected structural rivet. Check compatibility before fitting, as a general-purpose hand riveter may not be suitable.
Select your required rivet size and pack quantity from the available options. Contact Spalding Fasteners if you need help confirming the grip range, hole size or installation tool.
