Overview
The Wej-It wedge anchor model 3823 is a pre-assembled expansion anchor designed for reliable fastening in concrete, masonry, and similar materials. With dimensions of 3/8″-16 x 2-3/4″ (9.5mm x 69.9mm), this fully threaded fastener delivers secure anchoring with minimal installation effort. The product comes in a convenient box of 100 units, making it ideal for construction projects, industrial installations, and bulk procurement requirements.
Key Features
- Pre-assembled design — Reduces setup time and installation complexity
- Torque-controlled expansion — Provides consistent, predictable load performance across installations
- Safety shoulder feature — Unique shoulder in the expansion cone supports the clip to minimize bolt-end collapse and prevent clip slippage under ultimate loading conditions
- 3-dimple clip design — Enlarged dimples reduce slip and increase holding power in variable installation conditions
- High-strength construction — Fully threaded with optimized expansion cone geometry for maximum load capacity
- Bulk packaging (100 count) — Cost-effective for large-scale projects and inventory management
