The best match for T25 self-tapping screws in this selection is a Teks wood-to-metal screw: it has a T-25 star drive and is designed to fasten wood to metal without pre-drilling. The #10 screws suit common decking and framing jobs, while the longer #12 option offers more length. Two other picks use T20 drives, not T25, so choose them only if your driver bit matches.
| Product | Drive | Best For |
|---|---|---|
| Teks #10, 100 pieces | T25 | Typical wood-to-metal jobs |
| Teks #10, 300 pieces | T25 | Larger projects |
| Teks #12, 40 pieces | T25 | Longer fasteners |
| #8 pan head, 100 pieces | T20 | Low-profile metal fastening |
| #8 flat head, 100 pieces | T20 | Countersunk fastening |
Teks #10 T25 Screws, 100 Pieces
Best for: General wood-to-metal fastening when a 1-7/16-inch screw suits the material stack. This Teks option has a T-25 star drive and is designed to attach wood to metal from 1/8-inch material through 16-gauge without pre-drilling. Listed uses include roof or subfloor decking, trailer beds, and wood headers on steel frames.
The Climaseal coating is described as rust resistant for exterior applications. The 100-piece quantity is a practical middle ground between a small repair pack and a larger project supply. Choose this version if you want the stated T25 drive and a moderate quantity. The T-25 bit is sold separately, so it is not an all-in-one driver-bit package.
Teks #10 T25 Screws, 300 Pieces
Best for: Larger jobs that need the same #10 size and 1-7/16-inch length as the 100-piece option. Its T-25 star drive and wood-to-metal design support the same listed applications, including decking, trailer beds, and wood headers secured to steel framing. It is specified for metal from 1/8 inch to 16 gauge and does not require pre-drilling.
The Climaseal finish is described as rust resistant for exterior use. Choose this pack when the higher piece count better fits the project; the listed features do not indicate a different screw design from the 100-piece version. Avoid selecting it solely for quantity if you do not need that many fasteners. The T25 bit is sold separately.
Teks #12 T25 Screws, 40 Pieces
Best for: Wood-to-metal work where the longer 2-3/4-inch length is appropriate. This #12 screw has a T-25 star drive and is specified for attaching wood to metal from 1/8 inch to 16 gauge without pre-drilling. The listed examples include roof or subfloor decking, trailer beds, and wood headers attached to steel frames.
Its Climaseal coating is described as rust resistant for exterior applications, and the pack contains 40 screws. Choose it over the #10 options when the #12 size and longer length fit the fastening task. Confirm the required screw length and material thickness before use. The T-25 bit is sold separately.
#8 T20 Pan-Head Self-Drilling Screws
Best for: Buyers seeking short, pan-head self-drilling screws for metal, wood, or plastic who have a T20 bit. This 100-piece assortment is #8 x 1/2 inch and includes one T20 Torx bit. The product description says the drill-shaped point combines drilling and tapping, and the six-contact-point drive is intended to reduce stripping and cam-out.
The screws are described as 410 stainless steel with a black Dacromet coating for corrosion resistance in wet or outdoor conditions. However, this is not a T25 screw: its included bit is T20. Avoid it if your project specifically requires a T25 drive or a longer fastener.
#8 T20 Flat-Head Self-Drilling Screws
Best for: Metal fastening where a 3/4-inch #8 flat, countersunk head is the desired style and a T20 bit is available. The 100-piece pack includes one T20 bit. Its drill-shaped tip is described as combining drilling and tapping, while the Torx drive has six contact points intended to help limit cam-out.
The listed material is 410 stainless steel with a black Dacromet coating, described as suitable for wet and outdoor conditions. This option is better suited than the pan-head version when a countersunk head is needed. It is not T25; check the required drive size and head seating before choosing it.
Buying Guide: How to Choose T25 Self-Tapping Screws
Does the drive need to be T25?
Match the screw recess to the driver bit. The three Teks products listed here have T-25 star drives. The two #8 options use T20 drives, which are a different size. A Torx-style appearance alone does not confirm that a screw is T25.
Which length and size should you choose?
Compare screw length with the thickness of the materials being joined and the required embedment. The #10 Teks options are 1-7/16 inches long; the #12 option is 2-3/4 inches long. The #8 metal screws are shorter, at 1/2 inch or 3/4 inch. The product descriptions do not establish that these sizes are interchangeable.
When is a self-drilling screw useful?
Self-drilling points are designed to drill and form threads as the screw advances, reducing the need for a separately drilled pilot hole in suitable materials. The Teks listings specify wood-to-metal fastening, while the #8 listings describe use with metal, wood, and plastic. Follow the product’s stated material and thickness limits.
How should you compare coatings and quantities?
The Teks options list a Climaseal rust-resistant coating for exterior applications. The #8 screws list 410 stainless steel and black Dacromet coating. Choose based on the stated application and exposure, rather than assuming every coating suits every environment. For quantity, select 40, 100, or 300 pieces based on project needs and expected waste.
Frequently Asked Questions
Are T25 and T20 screw drives the same?
No. T25 and T20 identify different Torx drive sizes. Use a matching driver bit and confirm the drive size in the product description.
Do the Teks screws require pre-drilling?
The Teks product descriptions state that these wood-to-metal screws fasten without pre-drilling when used within their specified material range.
Which listed screw is longest?
The Teks #12 screw is 2-3/4 inches long. It is longer than the listed #10 and #8 options.
Do the Teks screws include a T25 bit?
No. The Teks listings state that the T-25 bit is sold separately. The #8 T20 assortments include a T20 bit, not a T25 bit.
Are all five options T25 screws?
No. The three Teks products are T25. The pan-head and flat-head #8 products use T20 drives, so they are alternatives only when T20 is acceptable.
