Stainless Storm Panel Screw Kit Simpson SPS25344KT

Description

Product Overview

The Simpson Strong‑Tie SPS25344‑KT Storm‑Panel Screw Kit is engineered for professionals who demand precision, durability, and ease of installation on a wide range of roofing applications. Each kit contains twenty‑five 1/4‑inch winged screws fabricated from 302 stainless steel, a material renowned for its superior corrosion resistance in coastal and high‑humidity environments. The screws measure 3‑7/16 inches in length, providing ample thread engagement for thick panel materials while maintaining a low profile that minimizes wind uplift. Complementing the screws are matching washered wing nuts, also constructed from 302 stainless steel, which lock securely in place without the need for additional tools. The package includes twenty‑five white plastic caps that conceal the fastener heads, delivering a clean aesthetic and additional protection against moisture ingress.

Beyond the core components, the kit is thoughtfully packaged to streamline the installation process. The screws are pre‑sorted and labeled for quick identification, reducing the time spent searching for the correct size on the job site. The washered nuts feature a self‑locking design that resists loosening under vibration, a critical feature for roofs exposed to high winds or seismic activity. The white caps are made from UV‑stable polymer, ensuring they retain their color and structural integrity even after prolonged sun exposure. All components meet or exceed industry standards for storm‑panel fastening, providing peace of mind that the installation will perform reliably for years to come.

Technical specifications for the kit are as follows: each screw is 0.2 inches in diameter, 3.5 inches in overall length, and weighs approximately 0.06 pounds, resulting in a total kit weight of 1.5 pounds. The product dimensions are 0.2 x 0.18 x 3.5 inches, making it compact enough to fit into standard toolboxes or on‑site storage containers. The kit is certified by Simpson Strong‑Tie, a trusted name in construction fasteners, and carries an ASIN of B008BQ2CTW for easy reference in online catalogs. With a best‑seller rank of #23 in the Panel Screws subcategory, the SPS25344‑KT has earned a reputation for quality and reliability among contractors and DIY enthusiasts alike.

Usage

This screw kit is ideal for securing metal roofing panels, siding, and cladding systems in both residential and commercial construction projects. The stainless steel construction makes it suitable for coastal installations where salt spray can accelerate corrosion, as well as for industrial facilities that require robust, long‑lasting fasteners. Installers can use the kit for new construction, retrofits, or repair work, benefiting from the consistent thread pitch and winged design that simplifies alignment and tightening. The 1/4‑inch washered wing nuts provide a secure, tool‑free locking mechanism, allowing for rapid installation without sacrificing strength.

Typical applications include attaching storm‑panel brackets to roof decks, fastening insulated metal panels to structural framing, and securing decorative metal cladding on commercial facades. The kit’s versatility also extends to specialty projects such as solar panel mounting, where the corrosion‑resistant screws protect against moisture while the winged nuts ensure a vibration‑free connection. For DIY homeowners, the included white caps offer a finished look that blends seamlessly with most roofing colors, eliminating the need for additional finishing materials.
