Bordo 1/2" x 13 UNC 2" Chrome Button Die
$54.93
The Bordo 1/2" x 13 UNC 2" Chrome Button Die is engineered for forming, repairing, and restoring Unified National Coarse (UNC) external threads. Designed for use with a die stock handle, this split circular button die is ideal for workshop, maintenance, and general-purpose threading tasks on softer metals and plastics.
Key Features:
- Thread Standard: Unified National Coarse (UNC), widely used across engineering, automotive, and manufacturing industries.
- Versatile Use:
- Excellent for chasing and cleaning damaged or contaminated external threads.
- Capable of cutting new threads on non-ferrous metals, aluminium, brass, plastics, and other lower tensile strength materials.
- Material: Durable chrome alloy for general workshop applications (not intended for high-precision or critical load-bearing thread production).
- Thread Form Details:
- Part of the Unified Thread Series introduced in 1948 to standardise thread forms across the USA, Canada, and the UK.
- Shares the same 60° thread angle as metric threads, as defined in JIS B0206.
- Coarse thread pitch provides superior stripping resistance in softer materials.
- Ideal for quick assembly/disassembly and applications exposed to dirt, minor thread damage, or corrosion.
Technical Specifications:
- Diameter (inch): 1/2
- Pitch (TPI): 13
- Thread Form: UNC
Applications:
UNC button dies are widely used in machinery repair, fabrication work, automotive maintenance, construction hardware production, and general engineering. Their coarse thread profile offers excellent durability and ease of use, particularly in softer materials where clean, strong thread engagement is required.
