Steel Shield Boss 20.3cm (8in) - 2.7mm (12 Gauge) - Outlet

Steel Shield Boss 20.3cm (8in) - 2.7mm (12 Gauge), Choice of Finish

Massive Construction and Authentic Appearance

This classic shield boss (umbo) is machine-pressed from approximately 2.7 mm (12 gauge) thick mild steel, ensuring exceptional strength and resilience even in demanding conditions. Its surface is then hand-hammered, giving it an authentic appearance that imitates a hand-forged surface and a rustic texture that sets your shield apart from mass-produced alternatives. The overall diameter of the umbo is circa 203 mm (8 inches), with the diameter of the central dome itself measuring approximately 140 mm (5.5 inches). The internal depth of the recess is about 50 mm (2 inches), providing ample space for a comfortable grip on the shield's handle with an adult hand.

This shield boss is available in two surface finish options (choose the one that best suits your project):

• Blued Surface with Hammered Imitation: A dark, matte appearance with a pronounced hammered texture for maximum historical authenticity (as seen in the accompanying product photos for this version).
• Brushed Steel: A lighter, metallic look with a finely brushed surface, which you can further customize or let shine in its natural form.

Easy Installation

For easy and secure attachment to your shield board, six holes, approximately 6.3 mm in diameter, are drilled into the wide flange of the umbo. The delivery includes a complete set of six sturdy rivets and corresponding washers, so you have everything you need for mounting readily available.

History and Function of Shield Bosses (Umbos)

Indispensable Element of Defence

The shield boss (umbo) was a key component of most types of shields used in Europe for centuries. Its main task was to protect the warrior's hand, which gripped a handle located directly behind the boss. Additionally, the umbo reinforced the central part of the shield and helped deflect blows away from the warrior's body.

Universal Use Across Cultures

Similar metal bosses are found on the shields of many cultures and periods – from Viking raiders and Celtic warriors to medieval knights. Their design might have varied, but the fundamental function of hand protection and shield reinforcement remained the same.

Did You Know? The Strength of 12 Gauge Steel

Did you know that 12 gauge steel (approximately 2.7 mm) is among the very robust materials used for producing replica armour and shields intended for full contact? Such a thick umbo provides a significantly higher degree of protection and resistance to deformation than bosses made from thinner sheets, which is crucial for safety in historical combat and reenactment.

Caring for Your Steel Shield Boss

This shield boss is a quality branded product from Lord Of Battles®. As it is made from carbon steel (mild steel, not stainless), it requires regular care:

• Keep Dry: Thoroughly dry the shield boss after each use, especially if it has come into contact with moisture (rain, sweat).
• Regular Oiling: Regularly, and always after drying, apply a thin layer of conservation oil (e.g., WD-40, Ballistol, or another gun oil) to the entire surface. This is particularly important for the brushed steel version; the blued surface offers some protection, but it too benefits from regular oiling.
• Inspection and Cleaning: Periodically inspect the surface. Carefully remove any incipient rust immediately (e.g., with very fine steel wool and oil for the brushed version; more gently for the blued version to avoid damaging the finish) and thoroughly re-oil the spot.
• Storage: Store the shield boss in a dry place.
