The LD-346 blind pop rivet assortment delivers the most-used rivet diameters and head styles in a single, clearly labeled package, giving fabricators and maintenance teams a ready supply for joining sheet metal, composites, and thin-walled components where only one side of the joint is accessible. Blind rivets (also called pop rivets) work by drawing a hardened mandrel through a tubular body with a rivet gun; the mandrel head flares the blind end of the body into a second head, clamping the work pieces together before the mandrel snaps off at a predetermined break point. This makes them indispensable for enclosed sections, hollow tubes, and panels that cannot be reached with a traditional solid rivet and bucking bar.

The assortment covers five standard diameters: 2.4mm (3/32") for light-gauge work and electronics enclosures, 3.2mm (1/8") for general sheet metal and ductwork, 4.0mm (5/32") for medium-duty brackets and automotive trim, 4.8mm (3/16") for structural sheet-metal assembly, and 6.4mm (1/4") for heavy-duty fabrication and trailer construction. A grip range of 1-20mm accommodates everything from single thin sheets to multi-layer stacks, and each diameter is available in multiple grip lengths so installers can match the rivet precisely to total material thickness for maximum clamp and shear strength.

Material configurations include the popular aluminum body with steel mandrel for a strong, lightweight, corrosion-resistant joint; an all-steel body with steel mandrel for higher shear and tensile loads in structural applications; and a stainless steel body with steel mandrel for environments demanding superior corrosion resistance such as marine, food-processing, and outdoor equipment. Head styles include the standard dome head for general clamping and a countersunk head for applications requiring a flush, low-profile finish. A copper body option is also available where galvanic compatibility or a distinctive appearance is required.

For wholesale buyers, the LD-346 supports full OEM customization including body and mandrel material combinations, head style, diameter and grip range, copper body options, logo printing, and tailored assortment compositions to suit specific industry needs. With an MOQ of 1000 pieces, mixed-order flexibility, and CE / ISO 9001 / RoHS / SGS compliance, it is an ideal stock item for industrial fastener distributors, automotive suppliers, and sheet-metal fabrication programs.
