Ingco 4.8mm x 12mm Open-End Blind Rivets – Premium Aluminum/Steel Pop Rivet Fasteners, 100-Piece Handy Bottle Pack (HWRT4801211)

Creating permanent, vibration-resistant sheet metal joints or reinforcing fragile plastic panels with standard screws or bolts can be highly inefficient and prone to loosening over time. Standard threaded fasteners require dual-sided access to tighten nuts, which is impossible when working on enclosed hollow profiles, ductwork, vehicle frames, or structural metal gates. The Ingco HWRT4801211 4.8mm x 12mm Open-End Blind Rivets provide an industrial-strength, one-sided fastening solution engineered to deliver rock-solid, permanent structural joints. Outfitted with an optimized open-end dome head matrix, these premium pop rivets allow mechanical fabricators, sheet metal installers, and repair crews to bind materials together with maximum sheer strength and total installation speed.

The exceptional clamping tension and corrosion resistance of these rivets stem from their high-quality aluminum body and hardened steel mandrel combination. The pliable aluminum alloy sleeve expands cleanly inside the pre-drilled workpiece, wrapping perfectly around the blind side of the material, while the high-tensile steel mandrel snaps predictably at its designated break point. Featuring a 4.8mm shank diameter and a versatile 12mm length, this sizing offers the ultimate trade-balance—providing high sheer resistance for sheet metal ductwork while accommodating a wide material grip range. Packed neatly inside a compact, moisture-proof plastic storage bottle, this 100-piece pack stays organized on busy worksites without spilling or getting lost in cluttered toolbags.

Key Features

• One-Sided Blind Fastening – Designed specifically for structural applications where access to the back or rear side of the workpiece is completely blocked.

• Premium Aluminum-Steel Material Matrix – Combines a lightweight, rust-resistant aluminum alloy sleeve with a heavy-duty steel mandrel to optimize sheer strength and durability.

• Classic Open-End Dome Head – Delivers a clean, flush-looking appearance on finished surfaces with an wide clamping face that distributes pressure evenly.

• Vibration-Proof Structural Holding Power – Unlike traditional metal screws, these rivets will not back out or rattle loose under severe mechanical vibration.

• Perfect 4.8mm x 12mm Dimensions – Ideal for joining medium-gauge metal sheets, framing channels, automotive panels, and heavy-duty plastic assemblies.

• Convenient Transparent Bottle Pack – Includes 100 pieces securely sealed inside a rugged plastic bottle to prevent accidental spills and resist garage humidity.
