Blue Square Drive Pocket Hole Screws — 360-Piece Assortment for Reliable Wood Joinery
When your woodworking joints keep stripping or your bits keep slipping mid-drive, the problem is usually the screw — not your technique. Whether you're a weekend DIYer building raised garden beds or a seasoned carpenter assembling cabinet frames, having the right pocket hole screw in the right size makes all the difference.
This 360-piece assortment includes five of the most commonly used coarse-thread pocket hole screw sizes — #8 x 1", #8 x 1-1/4", #8 x 1-1/2", #8 x 2", and #8 x 2-1/2" — all made from carbon steel with a blue oxide coating for corrosion resistance and long-term durability. A 100mm square drive bit is included to get you started right out of the box.
From softwood deck boards and plywood shelving to particleboard furniture and outdoor structures, these self-tapping screws drive cleanly without pre-drilling. The washer head design prevents overdriving, while the square drive recess eliminates bit cam-out — giving you confident, consistent results on every joint.
Compatible with all standard pocket hole jigs (Kreg-style and equivalent). Suitable for softwoods, plywood, and particleboard — indoor and outdoor use. Not recommended for hardwoods such as oak, maple, walnut, or cherry.

Frequently Asked Questions
What wood types are these screws compatible with?
These coarse-thread screws are designed for softwoods, plywood, and particleboard — both indoors and outdoors. They are not recommended for hardwoods such as oak, maple, walnut, or cherry, as the material is too dense for coarse-thread self-tapping screws and may cause the screw to strip or break.
Do I need to pre-drill before driving these screws?
No pre-drilling is required for softwoods and plywood. The sharp self-tapping point and deep coarse threads are designed to drive directly into the material. However, when working near the edge of a board or with denser softwoods, a pilot hole can help prevent splitting.
What pocket hole jig brands are these compatible with?
These screws are compatible with standard pocket hole jigs, including Kreg-style jigs and most equivalent brands. The #8 gauge and coarse thread profile match the standard pocket hole screw specification used across the industry.
What is the blue coating on the screws?
The blue finish is a blue oxide coating applied to the carbon steel. It provides a layer of oxidation resistance to help protect the screws from rust and corrosion, making them suitable for outdoor wood applications such as decks, garden beds, and exterior furniture.
Is the square drive bit compatible with standard drills and drivers?
Yes. The included 100mm square drive bit has a standard 1/4" hex shank, making it compatible with most cordless drills, impact drivers, and drill/driver combits. It fits any tool with a standard quick-release bit holder.
How are the screws organized in the case?
The kit comes in a reinforced storage case with thickened dividers and secure latches. Each compartment is clearly labeled on both the inner and outer lids, so you can quickly identify the size you need without emptying the case. The latches keep the lid closed securely during transport.
Can these screws be used for outdoor projects?
Yes. The blue oxide coating provides corrosion resistance suitable for outdoor use on softwood structures such as decks, fences, raised garden beds, and outdoor furniture. For prolonged exposure to moisture or coastal environments, consider applying a wood sealant to the finished project for added protection.
