Blind Rivets MEGA 4 x 12.5 mm aluminum, 800 pcs, model 59499

Pack of 800 MEGA blind rivets in size 4 x 12.5 mm with aluminum body, designed for creating permanent blind joints where access is available from one side only. These MEGA 4 x 12.5 mm aluminium blind rivets are intended for fastening thin metal sheets, non-ferrous materials and light assemblies. The kit provides a high quantity of consistent, vibration-resistant fasteners suitable for repetitive industrial or maintenance applications.

Advantages

The aluminum construction ensures a lightweight corrosion-resistant fastener that is compatible with non-ferrous materials and reduces the risk of galvanic corrosion when used with similar metals. Blind rivet design allows installation from one side, simplifying assembly in confined or hard-to-reach areas. The standardized 4 x 12.5 mm size delivers predictable grip and clamping force across similar material thicknesses, and the pack of 800 pieces supports high-volume jobs without frequent reordering.

Suitable for

• Fastening thin metal sheets and light panels
• Joining non-ferrous materials such as aluminum or copper
• HVAC fittings and ductwork assembly
• General repair, maintenance and light construction tasks

Key specifications

• Material: aluminum body
• Rivet dimensions: 4 mm diameter x 12.5 mm length
• Quantity: 800 pieces per pack
• Type: blind (pop) rivet for one-sided installation
• Suitable hole diameter: for 4 mm rivet shank

How to use

Drill a hole through the materials to be joined with the appropriate drill diameter for a 4 mm rivet shank. Insert the rivet into the aligned holes so the flange rests against the workpiece surface. Use a compatible hand or pneumatic rivet tool to pull the mandrel until the rivet body expands and forms a secure blind head on the far side. Remove the spent mandrel according to the tool's operation. Verify the joint for full seating and proper compression; replace any rivets that show improper deformation.

Usage recommendations

Store the rivets in a dry environment to prevent surface oxidation. Use rivets of the same material family where possible to minimize risk of galvanic interaction. For thicker materials or heavily loaded joints, confirm that the 4 x 12.5 mm rivet length provides adequate grip range before installation. Wear eye protection and follow tool safety guidelines during riveting.
