Timco Self-Drilling Screws for Wood to Metal, 5.5x100mm, 100pk

The Timco Metal Construction Timber to Light Section Screws are specifically designed for attaching wood to metal sections up to 5mm thick. These high-quality screws feature a coarse self-tapping thread with wing-tip design, which efficiently reams out timber to allow maximum RPM without burning out. When the wings contact the metal, they break off, enabling the screw to self-tap into the metal with precision.

Key Features:

• Exterior plating provides durable corrosion resistance, tested to withstand 500 hours of salt-spray exposure.
• Made from case & core hardened carbon steel for exceptional strength and longevity.
• Partially threaded design ensures optimal hold and reduced splitting in timber.
• Self-drilling No. 3 point eliminates the need for pre-drilling in most applications, saving time and effort.

Excellent for outdoor use, these screws are ideal for construction and carpentry projects where reliability and resistance to weathering are essential. The Philips recess and countersunk head with ribs ensure a secure and flush finish.
