It eliminates the need to source matching hardware separately, making it the convenient choice for professional framers and hobbyists alike.
The Silver Four-Hole Large L-Bracket 50mm with Screws is designed for zero-friction installation. The included pan-head self-tapping screws are precision-matched to the bracket’s 4mm holes, ensuring correct thread engagement and maximum joint strength in one step. No additional trips to the hardware store, no mis-matched screw sizes.
Arms: 50mm × 50mm | Width: 9mm | Inner step: 40mm | Thickness: 0.6mm | Holes: 4 × 4mm | Finish: Zinc-plated | Included: 2× pan-head self-tapping screws.
Place the Silver Four-Hole Large L-Bracket 50mm with Screws at the corner junction with both arms flush on the frame members. Drive the included screws using a Phillips driver. For the next size down, see our L39 Small 38mm Bracket. Find corner brace kits at Amazon’s corner brace kit selection.
Q: How many per package?
A: 1 bracket + 2 screws. Buy 4 units for a complete 4-corner frame.
Q: Are screws suitable for hardwood?
A: Pre-drill a 2mm pilot hole for hardwood; self-tapping works directly in softwood.
Q: Can it be used on MDF?
A: Yes — coarse-thread self-tapping screws grip MDF well.

Are the screws included with L38 suitable for hardwood frames?
Are the screws included with L38 suitable for hardwood frames?
The included self-tapping screws work well in softwood frames without pre-drilling. For hardwood mouldings, pre-drill a 2mm pilot hole for cleaner installation and to avoid splitting the wood.
Can L38 be used on MDF frame components?
Yes. The 0.6mm plate and 4mm hole size suit MDF corners well. Use the included self-tapping screws with coarse thread for better grip in MDF material.
