What is BS 1127-1 - Hand- and machine-operated circular screwing dies and hand-operated die stocks about?
BS 1127 is a British standard that discusses screwing dies and dies nuts. BS 1127-1 is the first part of the multi-part series that outlines the general dimensions of hand-operated and machine-operated screwing dies to manufacture hand- and machine-operated circular screwing dies and hand-operated die stocks of the correct size.
These dimensions, established as a function of the thread diameter and pitch, are the following:
- Outside diameter
- Thickness
- Cutting portion length
- General dimensions of attachment
BS 1127-1 also gives the interchangeability dimensions of hand-operated die stocks.
BS 1127-1 applies to screw dies intended for the manufacture of the following threads:
- ISO metric threads, coarse thread, from M1 to M68, and fine thread, from M1 to M56
- ISO inch threads, “Unified coarse” series (UNC), from No. 1 – 64 to 2 3/4 – 4, and “Unified fine” series (UNF), from No. 0 – 80 to 1 1/2 – 12
Who is BS 1127-1 - Hand- and machine-operated circular screwing dies and hand-operated die stocks for?
BS 1127-1 on hand- and machine-operated circular screwing dies and hand-operated die stocks are useful for:
- Circular screwing die manufacturers
- Die stocks manufacturers
- Design engineers
Why should you use BS 1127-1 - Hand- and machine-operated circular screwing dies and hand-operated die stocks?
Screwing dies is either of the two parts of a hollow, internally threaded tool used to cut a screw thread. A die nut also known as a thread chaser is used for sharpening an existing thread. It is run over threads that may have been damaged or blunted overtime to correct them to their original condition.
BS 1127-1 assist you with ISO metric threads on the coarse thread and fine thread, ISO inch threads on the “unified coarse” series (UNC) and “Unified fine” series (UNF), die stocks interchangeability dimensions, and marking of hand- and machine-operated circular screwing dies and hand-operated die stocks. This assists in manufacturing highly durable, efficient and high standard hand- and machine-operated circular screwing dies and hand-operated die stocks.
With obedience and compliance to BS 1127-1, you can enhance the efficacy of your hand- and machine-operated circular screwing dies and hand-operated die stocks.
