Get quoteThe Silver Round-Hole L-Bracket Corner Brace 40mm with Screws (SKU: L48) is the screw-inclusive version of L47, delivering the complete installation package for versatile multi-hole corner joinery. The 40×40mm, 0.7mm zinc-plated bracket with its distinctive 6mm round cutout and 4mm standard holes ships with 2 pan-head self-tapping screws for immediate, no-additional-hardware installation.
The Silver Round-Hole L-Bracket Corner Brace 40mm with Screws combines structural corner bracing with wire-routing capability from the moment it is unpackaged. Install the bracket with the 2 included screws through the 4mm holes, then route picture hanging wire, cable management ties, or secondary fasteners through the 6mm round cutout — all without requiring any additional hardware beyond what is included.
Arms: 40mm × 40mm | Corner step width: 20mm | Arm width: 9mm | Thickness: 0.7mm | Holes: 4mm (standard) + 6mm (cutout) | Finish: Zinc-plated | Included: 2× pan-head screws.
The Silver Round-Hole L-Bracket Corner Brace 40mm with Screws is installed in the same manner as standard L-brackets, with the added step of routing wire or other elements through the 6mm cutout as required. For the next design variant, see our L49 Silver Cross-Slot 45mm Bracket. Browse round-hole L-brackets at Amazon’s round-hole corner brace kits.
Q: Same as L47 with screws?

Q: Load capacity?
A: Medium-weight frames. For heavy-duty use, step up to L35/L36 (1.2mm plate).

Is L48 identical to L47 except for the included screws?Is L48 identical to L47 except for the included screws?
How do the included screws interact with the 6mm round cutout?
How do the included screws interact with the 6mm round cutout?
The 2 screws included with L48 are sized for the standard 4mm holes — not the 6mm cutout. The large cutout remains available for wire routing, cable ties, or additional custom fasteners.
What load can L48 support?
Based on the 0.7mm plate and 40mm arm specifications, L48 is suitable for medium-weight picture frames and canvas works. For heavy-duty corner reinforcement, consider the 1.2mm thick L35 or L36.
