Fastener Manufacturing & Thread Rolling calculator
Wire Coil Yield Calculator
Wire yield tells you how much of the issued coil became usable blanks or finished fasteners. Enter the usable output, total coil issued, and target yield to see the yield rate and the gap to your standard.
What this calculator does
- Calculate wire coil yield from usable fastener blank weight or count versus total coil issued, with a target yield comparison.
- Use it when reviewing wire yield after drawing, cut-off, heading setup, coil butt loss, or fastener production scrap.
- Compares usable output from a coil with total wire issued to calculate material yield and target gap.
Formula used
- Wire coil yield = usable output from coil รท total wire issued
- Gap to target = target wire coil yield - calculated yield
Inputs explained
- Usable wire converted to accepted output: undefined
- Total wire issued from coil: undefined
- Target wire coil yield: undefined
How to use the result
- Use it for coil reconciliation, scrap reviews, material purchasing, and heading setup improvement work.
- It requires the same unit for usable output and total wire issued; do not mix pounds and pieces without converting by blank weight.
Common questions
- Should I use pounds or pieces? Use either, but keep both inputs in the same unit. Pounds are best for coil reconciliation; pieces work if blank weight is known and consistent.
- What belongs in total wire issued? Include the coil weight or count released to the job, including setup wire, butt ends, samples, and any material scrapped before accepted output.
- What causes low wire coil yield? Common causes include cut-off variation, setup scrap, feed problems, die breakage, coil butt loss, mixed material, and rejects found after heading or thread rolling.
- How should the result be used? Use the yield and gap to update scrap assumptions, investigate material loss, and decide whether quoted wire usage still protects margin.
