The JRP Riveting Products 4.8 x 20mm rivets are essential hardware for professionals and DIY enthusiasts requiring a heavy-duty, permanent fastening solution for metal sheets or thick materials. Featuring an extra-large flange head, these rivets provide superior surface area contact for improved grip and load distribution, though users should ensure their rivet gun is compatible with the 4.8mm diameter shaft before beginning their project.

These rivets have a shaft diameter of 4.8mm.
Yes, provided your manual rivet gun has a 4.8mm nosepiece adapter installed.
The extra-large flange provides more surface area, which improves the clamping force and helps prevent the material from tearing around the hole.
They are designed for durability, but should be kept in dry conditions to maintain their silver finish and structural integrity over time.
The 20mm length is ideal for joining thicker materials or multiple overlapping layers where shorter rivets would lack sufficient grip.
Ensure the rivet gun is fully seated against the flange and the material layers are clamped together tightly before triggering.
Check that the pilot hole diameter is correct. If the hole is too small, the force required to pull the mandrel will exceed its structural limits.
Verify that the material thickness does not exceed the rivet's maximum grip range, which would prevent the back head from fully expanding.
To achieve the best results, use a high-quality hand-operated or pneumatic rivet gun equipped with a 4.8mm (3/16 inch) nosepiece. Before riveting, ensure the target surfaces are clamped tightly together to prevent gaps. Drill a pilot hole slightly larger than 4.8mm to allow for a smooth fit. Post-installation care is minimal as these are permanent fasteners; however, check for any deformation around the flange if used on soft materials to avoid crushing the substrate. Always keep the rivets in a dry, low-humidity environment to maintain the finish and prevent surface corrosion.
