Explore our premier selection of 4.8mm (3/16") trifold blind rivets, lantern rivets, and specialized industrial fasteners manufactured under IATF 16949 quality controls.
A deep dive into the mechanical load distribution, material science, and operational efficiency of 4.8mm (3/16") lantern rivets across modern assembly industries.
In modern industrial assembly, the demand for lightweight, high-shear, and soft-material compatible blind fasteners has led to a paradigm shift. Traditional solid or open-end rivets often exert localized point pressure, leading to material cracking, pull-through, or structural deformation when joining delicate substrates such as plastics, fiberglass, thin sheet metals, or composite panels. The 4.8mm Trifold Blind Rivet (frequently designated as 3/16 inch lantern rivets or bulb rivets) has emerged as the definitive global engineering standard to solve this challenge.
Manufactured under stringent process controls by leading Chinese suppliers such as WUXI AIPLLE METAL PRODUCTS CO., LTD., 4.8mm trifold rivets feature a uniquely slotted alloy body. Upon actuation, the mandrel head pulls back into the rivet body, forcing the sleeve to split radially into three distinct anchor legs. This tri-folding expansion forms a large, flat secondary bearing head on the blind side, expanding the load-bearing area by up to 300% compared to standard blind rivets.
Rigorous mechanical metrics designed for structural engineers, procurement specialists, and automotive quality managers.
| Rivet Body Dia (mm / inch) | Hole Size Range (mm) | Rivet Body Material | Mandrel Material | Grip Range (mm) | Shear Strength (N) | Tensile Strength (N) |
|---|---|---|---|---|---|---|
| 4.8mm (3/16") | 5.0 - 5.2 mm | Aluminum Alloy 5052 / 5056 | Zinc Plated Carbon Steel / Stainless | 1.5 - 6.5 mm | ~ 1,450 N | ~ 2,100 N |
| 4.8mm Extended | 5.0 - 5.2 mm | Aluminum Alloy 5052 | Phosphate / Zinc Plated Steel | 4.0 - 9.5 mm | ~ 1,500 N | ~ 2,200 N |
| 4.8mm Large Flange | 5.1 - 5.3 mm | Aluminum Alloy 5056 (High Mag) | Zinc Plated Steel Mandrel | 1.0 - 7.0 mm | ~ 1,600 N | ~ 2,350 N |
| 4.8mm Sealed Trifold | 5.0 - 5.2 mm | EPDM Washer + Aluminum Body | Stainless Steel 304 / Steel | 2.0 - 8.0 mm | ~ 1,550 N | ~ 2,150 N |
