FULLERKREG 1121 Speed Fastener (No Stock, Can Be Developed)

FULLERKREG 1121 Speed Fastener

The FULLERKREG 1121 Speed Fastener is a dome-head expansion rivet engineered for fast, low-cost assembly on soft or brittle materials. Its internally tapered bore lets it expand radially during installation, delivering a consistent, controlled clamp without the localized stress that welding or conventional rivets can cause. This item is currently not stocked but can be developed to order — contact FULLERKREG for tooling lead time and minimum order quantity.

Product Overview

  • Head form: Dome / mushroom head
  • Material: Low carbon steel (SAE 1008 / EN 10263-2 C8C, DIN 10263-2 C8C, Qst 34-3)
  • Surface finish: Zinc plated, clear trivalent passivated
  • Nominal size range: 1/8" to 1/4" (3.2 mm to 6.4 mm)
  • Installation method: Repetition mandrel system for high-speed manual or automated placement; bowl-feed compatible for high-volume automated lines
  • Availability: No stock on hand — available as a custom development order

Why Choose a Speed Fastener

  • Internally tapered bore gives a consistent light clamp that protects soft or brittle materials from damage.
  • Light clamping force makes it well suited for use as a pivot pin or hose tail.
  • Expands radially on installation to maximize hole fill and joint retention.
  • Lower installed cost than welding or nail-type rivets.
  • Placed with a repetition mandrel system for high-speed assembly, or bowl-fed for automated high-volume production.
  • Common in automotive components, electronics enclosures, sheet metal assemblies, electrical switchgear, domestic appliances, and light fabrication work.
