The TIMco Hex Flange Advanced Coach Screws deliver professional-grade fastening performance for he...The TIMco Hex Flange Advanced Coach Screws deliver professional-grade fastening performance for heavy-duty construction and installation applications. Featuring a hex flange head and aggressive slash point tip, these screws represent the modern evolution of traditional DIN 571 coach screws. Engineered for efficiency, these screws install three times faster than standard coach screws and are fully compatible with power tools. The aggressive slash point ensures easy driving while reducing splitting across softwood, hardwood, man-made board, and masonry applications when paired with nylon plugs. Zinc plated with yellow passivation, these 10 x 100mm screws provide enhanced corrosion resistance for long-term reliability in demanding environments. Each box contains 50 screws, offering consistent performance for professional tradespeople and DIY installations alike.
Features & Benefits:
* Three times faster installation than standard coach screws for improved productivity.
* Aggressive slash point tip drives easily and reduces material splitting.
* Hex flange head provides superior stability and torque transfer during installation.
* Compatible with power tools for efficient fastening workflows.
* Zinc plated and yellow passivated finish delivering enhanced corrosion resistance.
* Suitable for softwood, hardwood, man-made board, and masonry (with nylon plug) applications.
Specifications:
* Point Type: Single Slash.
* Size: 10 x 100mm.
* Box Quantity: 50.
The TIMco Hex Flange Advanced Coach Screws are designed for professionals and serious DIYers seeking efficient and reliable fastening for heavy-duty applications. Their key benefit is a significantly faster installation time compared to traditional coach screws, enabled by an aggressive slash point and compatibility with power tools. A potential caveat is that for masonry applications, they require the use of nylon plugs for optimal performance.

FAQs
How do these screws differ from standard DIN 571 coach screws?
These advanced coach screws feature an aggressive slash point tip for easier driving and reduced splitting, a hex flange head for better torque transfer with power tools, and are designed for significantly faster installation, up to three times quicker than traditional types.
Can I use these screws in masonry?
Yes, they can be used in masonry, but it is essential to use them in conjunction with appropriately sized nylon wall plugs to ensure a secure fixing.
What type of tools are recommended for installation?
They are designed for use with power tools such as impact drivers or drills fitted with a compatible hex bit or socket. A manual socket wrench can also be used.
What does 'yellow passivation' mean for corrosion resistance?
Yellow passivation is a chemical treatment applied after zinc plating, providing an additional layer of protection against corrosion. This finish is generally considered to offer good resistance for most general building applications.
What is the box quantity for these screws?
Each box contains 50 TIMco Advanced Coach Screws.
Are these screws suitable for exterior use?
Yes, the zinc-plated and yellow-passivated finish offers enhanced corrosion resistance, making them suitable for many exterior applications. However, for highly exposed or corrosive environments, consider alternatives like stainless steel.
Troubleshooting
Screw is difficult to drive.
Ensure you are using the correct size pilot hole for the material. For hardwoods or dense materials, a slightly larger pilot hole may be needed. Check that your power tool is functioning correctly and has adequate power.
Material is splitting around the screw.
Pre-drill a pilot hole. If splitting persists, ensure the pilot hole is appropriately sized (usually slightly smaller than the screw shank). Avoid over-tightening the screw.
Power tool bit is slipping on the screw head.
Ensure you are using the correct size and type of hex driver bit. Check the condition of both the bit and the screw head for any damage or debris. Apply firm, consistent pressure.
Screw does not feel secure in masonry.
Verify that a nylon plug is being used and that it is the correct type and size for the hole drilled. Ensure the plug is fully seated before driving the screw.
Pros and Cons
Pros
Installs up to three times faster than standard coach screws, saving significant time on projects.
The aggressive slash point tip minimizes wood splitting, leading to cleaner installations.
Hex flange head allows for high torque application with power tools.
Yellow passivation provides excellent corrosion resistance for durability.
Versatile for use in various timber types and masonry (with plugs).
Cons
Requires a pilot hole for some harder woods or masonry applications to prevent splitting.
Yellow passivation, while offering good corrosion resistance, may not be suitable for all aesthetic requirements compared to stainless steel.
Requires appropriate tooling (hex driver/socket) for installation, typically a power tool.
Setup, Compatibility & Care
Setup:
Pilot Holes: For hardwoods, engineered boards, or dense softwood, it is recommended to pre-drill a pilot hole slightly smaller than the screw's core diameter to prevent splitting and ease driving. For masonry, always use an appropriate masonry drill bit to create a hole suitable for a nylon plug.
Tooling: Utilize a hex driver bit or socket wrench that matches the head size of the screw (typically 10mm or 13mm for this size, confirm before use).
Power Tool Usage: Engage the power tool at a moderate speed initially, increasing as the screw penetrates. Ensure the tool is set to a suitable torque setting to avoid over-driving.
Compatibility:
Timber: Softwood, hardwood, and man-made boards (e.g., MDF, plywood).
Masonry: Compatible when used with appropriate nylon wall plugs.
Tools: Impact drivers, drills with clutch settings, socket wrenches.
Care:
Store screws in a dry environment to maintain the integrity of the zinc plating.
Clean any debris from the screw head before driving to ensure optimal tool engagement.
The yellow passivation offers good corrosion resistance, but for highly aggressive environments (e.g., coastal or chemically exposed), consider additional protective coatings or stainless steel alternatives.
