Dorman 963-258D Rivet Nut M4-0.7 Metric Threaded Insert

The Dorman 963-258D is an M4-0.7 metric rivet nut (also known as a rivnut or blind nut) designed to create a secure, internally threaded insert in materials where only one side is accessible. Precision-manufactured from corrosion-resistant tubular steel, this fastener installs into a pre-drilled hole and anchors entirely from a single side — no access to the reverse face required.

Key Features:

• Thread Size: M4-0.7 metric
• Inside Diameter: 3.2 mm
• Body Depth: 9.6 mm
• Corrosion-resistant tubular steel construction
• Installs from one accessible side into a pre-drilled hole
• Creates a strong, reusable internal threaded insert
• Ideal for thin-gauge panels, sheet metal, and other single-sided applications

Rivet nuts are a reliable solution for adding threaded fastening points to surfaces where a standard nut cannot be used. The Dorman 963-258D is a direct replacement for OEM-style blind nut hardware commonly found in automotive, marine, and general mechanical repair applications.
