The Complete Guide to Metal Building Fasteners: Choosing the Right Hardware for Your Project
When it comes to metal building construction, the smallest components often carry the greatest responsibility. At Infinity Building Supply in Mineola, TX, we’ve seen firsthand how the right fasteners can make the difference between a structure that stands strong for decades and one that fails prematurely. That’s why we’ve made it our mission to provide East Texas builders and contractors with the highest quality fasteners specifically designed for metal building applications.
With years of experience serving the construction community, we understand that choosing the right fastener isn’t just about finding something that fits—it’s about ensuring long-term structural integrity, weather resistance, and cost-effectiveness. Our comprehensive selection includes everything from self-drilling screws and Tek screws to specialized bolts, nuts, and washers, all carefully chosen for their performance in Texas’s challenging climate.
At Infinity Building Supply, we don’t just sell fasteners—we provide solutions that help ensure your metal building project exceeds expectations while staying within budget.
Understanding Self-Drilling Screws: The Workhorse of Metal Construction
Self-drilling screws, often called Tek screws, represent one of the most significant advances in metal building fastener technology. These versatile fasteners combine drilling, tapping, and fastening into a single operation, dramatically reducing installation time and labor costs. EJOT self-drilling screws connect components in one work step: they drill, form the thread and fasten.
The key to understanding self-drilling screws lies in their innovative tip design. Tek screws feature a tip that mimics the appearance and functionality of a drill bit, creating the correctly sized hole for the thread to catch without requiring pre-drilling.
For Texas builders working with varying steel thicknesses, choosing the right drill point is crucial. Tek screws are identified by a number from 1-5 which indicates the length of the flute, determining the level of metal thickness it can drill through. Point #1 handles thin materials up to 0.050 inches, while Point #5 can drill through steel up to 0.500 inches thick.
Head Styles and Applications
The head style you choose significantly impacts both functionality and appearance. The most common metal roofing screws are hex head, hex washer head, and pancake head. Hex washer heads provide excellent bearing surface and weather sealing, while pancake heads offer a lower profile for aesthetic applications.
Corrosion Resistance: Critical for Texas Climate
East Texas’s humid subtropical climate, combined with occasional severe weather, creates challenging conditions for metal building fasteners. Cheap screws rust and spread corrosion to steel panels, creating both aesthetic and structural problems. Once rust forms, it spreads and may eventually cause serious structural problems in metal buildings.
Zinc-Plated Fasteners
For most East Texas applications, zinc-plated fasteners provide excellent protection against corrosion. EJOT self-drilling screws are available in zinc-plated steel for unweathered areas and stainless steel for weather-exposed areas. The zinc coating acts as a sacrificial barrier, protecting the underlying steel even if the coating is slightly damaged.
Stainless Steel Options
For coastal areas or highly corrosive environments, stainless steel fasteners offer superior longevity. Stainless steel 304 fasteners are highly rust-resistant and are a great option for drier climates. Stainless steel 316 is the recommended fastener choice for humid climates. While the initial cost is higher, stainless steel fasteners often prove more economical over the building’s lifetime.
Specialized Fastener Applications
Self-Tapping vs. Self-Drilling
While often confused, self-tapping and self-drilling screws serve different purposes. Self-tapping screws are good for use with metals, various types of plastics, and cast or forged materials, but require pre-drilled holes. Self-drilling screws eliminate the need for pre-drilling entirely and can fasten metal to metal, wood to metal, and work well with light, low-density materials.
Heavy-Duty Applications
For structural connections and heavy steel applications, beam buster screws provide exceptional strength. These fasteners feature enhanced drill points and higher tensile strength for demanding applications.
Sealing Washers: Your First Line of Defense
No discussion of metal building fasteners is complete without addressing sealing washers. Quality sealing washers made of EPDM synthetic rubber withstand heat extremes, ozone deterioration, and ultraviolet rays. EPDM washers weather the years extremely well and provide the critical barrier that prevents water infiltration.
Proper Installation and Sizing
Even the highest quality fasteners can fail if improperly installed. Key installation principles include:
- Ensuring perpendicular alignment to prevent thread stripping
- Using appropriate drill speed to prevent overheating
- Achieving proper torque without over-tightening
- Maintaining at least one inch of penetration into the fastening material
Proper fastener length is crucial for structural integrity. The right fasteners must be long enough to go through all materials plus account for drill bit length on self-drilling screws.
Local Considerations for East Texas Builders
Building in East Texas presents unique challenges that influence fastener selection. Our region’s high humidity, occasional severe storms, and temperature fluctuations demand fasteners that can handle thermal expansion while maintaining their protective coatings.
Agricultural buildings face additional challenges from corrosive agricultural chemicals and livestock-related moisture. Industrial applications may encounter additional environmental stressors requiring upgraded fastener materials.
At Infinity Building Supply, we understand these local conditions and stock fasteners specifically suited for East Texas applications. Our team regularly works with local contractors and provides specific recommendations based on your project’s location and intended use.
