#14 Size 1 1/4ft Length Hex Washer Head Self Drilling Screws - Durable

Our review of the Hex Head Self Tapping Drilling Screws finds them most useful for contractors and dedicated DIYers who need a reliable, corrosion-resistant fastener for metal-to-metal or metal-to-wood work. The single biggest reason to buy is the combination of a self-drilling point and 410 stainless steel construction, which eliminates pre-drilling for many sheet metal tasks while resisting rust in outdoor environments. In practice these screws speed installations for roofing, gutter guards, and e-track mounting where a secure, long-lasting hold is required.

Key Features

• Self-drilling tip: Cuts its own pilot hole to save time and remove the need for a separate drilling step on thin metal and many composite surfaces.
• 410 stainless steel: Provides good corrosion and heat resistance so fasteners last in outdoor and semi-exposed installations.
• Hex washer head: Delivers greater driving torque and a flatter bearing surface that helps seat the screw firmly against metal or wood.
• #14 size, 1 1/4' length: Offers a robust shank and enough penetration for sheet metal, gutter work, and light framing without excessive protrusion.
• Pack of 100: Supplies enough fasteners for medium-sized jobs so you do not run out during an installation.

Who It's For

These screws are ideal for roofers, metal fabricators, fence installers, and DIYers working on gutter guards, e-track mounting, piping supports, and similar tasks where a reliable metal-to-metal or metal-to-wood connection is required. The self-drilling feature particularly benefits users who value speed and fewer tools on the jobsite.

Those who need stainless fasteners for heavy structural suspension or extremely high-corrosion marine use should evaluate grade requirements and consult specifications; for light to moderate outdoor exposure and general construction, the 410 stainless offers an excellent balance of strength and corrosion resistance.
