Paulin One-Way Security Screws Stainless Steel
Paulin's stainless steel one-way screws are positioned as the premium choice for bird cages because they combine marine-grade corrosion resistance with a clean, tamperproof head that discourages theft and unauthorized access. They tend to cost more than basic economy options but outperform others on longevity and rust resistance, making them especially suited to outdoor aviaries compared with Hillman's budget-focused line or Prime-Line's sheet-metal specialty fasteners.
