Kvohlum: 100-Pack #14 x 1-1/4″ Self Drilling Screws
Product highlights: The screws are made from 410 stainless steel for corrosion resistance and durability. They feature a hex washer head and a 1/4″-14 thread with a 1-1/4″ length. A flanged head design helps distribute load and reduce pull-through on thin materials. The package includes a plastic storage container for organization and quick access. The self-drilling point minimizes pre-drilling, promoting faster assembly and reducing material damage during installation.
Hillman: Zinc Hex Washer Head Self Drilling Screws
Product highlights: Hillman’s 1/4″-14 x 1′ screws are designed for use in wood, fiberglass, and metal. They use coarse threads and a self-drilling point that eliminates the need for a pilot hole. The hex drive provides straightforward, secure installation with reduced risk of cam-out. The zinc plating offers basic corrosion resistance suitable for general indoor applications and light outdoor use when protected from harsh elements.
Mellewell: 50-Pack #14 x 1-1/4″ Self Drilling Screws
Product highlights: Made from 410 stainless steel with a bright finish, these 1-1/4″ screws use an external hex drive, with a hex head diameter around 9.7 mm and a head washer diameter of about 12.8 mm. The 5.6 mm head height ensures a strong seating. This pack is designed for durable metal-to-metal connections and provides reliable performance in challenging environments where corrosion resistance matters.
Kvohlum: 60 Pieces Black Hex Washer Head Screws
Product highlights: These 410 stainless steel screws come with a black coating to boost corrosion resistance and a hex washer head for secure torque. The 1-1/4″ length matches typical thin gauge metal assemblies. A flanged design helps to spread load on sheet metal surfaces and reduces the risk of pull-out after installation. The 60-piece package makes it suited for smaller projects or stocking up a workstation.
MewuDecor: #14 x 1″ Hex Washer Self Drilling Screws
Product highlights: MewuDecor provides 410 stainless steel screws with a 1″ length suitable for light metal projects. They feature a hex washer head for secure drive and a drill-point design that enables direct entry into metal without pre-drilling. The package size of 50 pieces makes it appropriate for smaller repair tasks or hobby projects, ensuring consistent performance across installations.
ASMC Industrial: 1/4″-14 x 1-1/2″ Self-Drilling Screws
Product highlights: ASMC Industrial offers a 1-1/2″ length with a 3-point tip designed to optimize penetration without pre-drilling. The zinc-plated low carbon steel construction provides basic corrosion resistance for general uses. The hex washer head ensures secure fastening and better torque control, helping to minimize stripping during installation. This pack is well-suited for maintenance and industrial applications where consistent performance is essential.
Wensilon: 250-Pack #14×1″ Hex Washer Head Self Drilling Screws
Product highlights: Wensilon provides a high-volume option in 410 stainless steel for strong, durable performance. The 1″ length with hex washer head is ideal for projects involving metal or non-metal substrates. The material’s corrosion resistance and robust construction offer dependable long-term use in demanding environments, including construction and manufacturing settings.
Uxcell: #14 x 1″ Self Drilling Screws with EPDM Washer
Product highlights: Uxcell combines a #14 thread with a 1″ length and a hex washer head featuring an EPDM rubber washer. The EPDM washer creates a tight seal to prevent leaks and loosening in metal-to-metal assemblies, making these suitable for roofing or exterior metal connections. The zinc-plated carbon steel construction offers corrosion resistance for protected outdoor applications.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Stainless steel (410) provides strong corrosion resistance and durability in many environments, while zinc-plated steel offers basic protection for indoor tasks. Choose stainless for outdoor or high-moisture use.
- Head design and sealing: Hex washer heads with flanged bases distribute load and reduce pull-out risk. If sealing is important, consider screws with EPDM or rubber washers for leak prevention.
- Drill point and ease of installation: A true self-drilling point eliminates pre-drilling, saving time. A three-point tip (as in some ASMC Industrial options) can enhance starting torque and centering.
- Length and thread: Ensure the length is sufficient to penetrate the material stack without breaking through. A 1/4″-14 thread is standard for metal-to-metal fastenings; check material thickness to select the correct length.
- Quantity and packaging: For larger projects, bulk packs (250 pcs or more) reduce reordering. For small repairs, 50–60 piece packs are often enough.
- Coatings and appearance: Black-coated versions offer additional corrosion resistance and a low-reflective finish suitable for certain settings, but confirm compatibility with your application.
- Compatibility with driving tools: Hex driver or bit size compatibility matters for ease of use and minimizing cam-out. Verify your driver’s torque rating to avoid stripping.
When selecting screws, balance cost with the expected service life, installation speed, and the environment. For outdoor or exposed installations, prioritize stainless steel with corrosion resistance. For interior projects, zinc-coated fasteners may suffice. Consider the presence of seals or washers if a leak-proof joint is necessary. Always verify that the screw length and thread match the material thickness you plan to fasten.
