Clench Nail (NLM-2FC690)
An iron clench nail found near Torksey, Lincolnshire
Clench nails were used in clinker-style ship-building from the 7th century to the 15th and also for domestic purposes, in which clench nails might appear where ship timber has been reused. Clinker ship-building involved building the ship’s hull first out of layered planks attached to the keel and held together using clench nails. Clinker-built boats and ships are particularly associated with the Vikings.
