Overview
The ITW Buildex 1044000 is a premium TEKS 3 Maxiseal self-drilling screw engineered for demanding steel-to-steel fastening applications. This hex washer head design combines a #3 self-drilling point with an integral neoprene sealing washer, reducing assembly steps and improving weatherproofing in roofing and metal wall systems. The Climaseal coating provides enhanced corrosion resistance, making these screws ideal for long-term outdoor exposure.
Key Features
- TEKS 3 Self-Drilling Point: Fast-starting drill point engineered to minimize walking and deliver consistent hole initiation in steel from 0.036″ to 0.210″ thick
- Integral Neoprene Sealing Washer: Factory-integrated washer eliminates the need for separate washers and gaskets, ensuring consistent sealing and faster installation
- Hex Washer Head Design: Larger bearing surface reduces fastener seating issues and distributes load more evenly on thin metal substrates
- Climaseal Coating: Proprietary gray corrosion-resistant finish extends service life in harsh outdoor and industrial environments
- Bulk Packaging: Supplied in a 25-piece box for convenient job-site storage and portability
