The T.N.T 1.5mm flexible Allen spanner combines a steel shank with an aluminum handle for durability and lightweight handling. Its spring-loaded flexible shank bends at various angles, enabling access to tight or awkward spaces. Designed for precise and secure Hop-up chamber adjustments, it features a Torque-Limited Function that prevents over-tightening, protecting bolts from damage and ensuring a secure fit without the need to disassemble your replica.
