Linear weigh fillers
Good for moderate outputs, multiple products and controlled dry product dosing.

Screws, nails and small parts weigh fillers
Fill hardware, fixings and small parts by target weight where counting and weighing routes need comparing.
Planning the right weigh filling route
Small parts such as screws, nails, washers and fixings can often be packed by weight, especially where exact piece count is less critical than pack value or total weight.
A practical route considers part size, sharp edges, bulk density, pack opening and whether the product marks or damages the packing equipment.
For some products, counting may be a better method. Lancing can help compare the weighing route against pack expectations.
Key buying checks
- Check whether weight or count is the commercial requirement.
- Review sharp edges and wear on contact parts.
- Confirm pack opening and target weight.
- Plan noise, feed control and operator access.
Routes to compare
Machine options to shortlist.
Hardware applications may use weigh filling, counting or a combination depending on pack promise.
Multihead weighers
Useful where speed, accuracy and product combination are central to the project.
View routeAuger fillers
Often compared for powders, fine ingredients and products that need screw dosing.
View routeVFFS weigh lines
For automatic bag forming, weighing, filling and sealing from film reels.

Questions before choosing a weigh filler.
Short answers for production teams comparing dry-product weighing and filling routes.
What information is needed for screws, nails and small parts weigh fillers?
Useful details include the product name, bulk density if known, target fill weight, acceptable tolerance, pack format, output per minute or hour and whether the line must connect to feeding, sealing, capping, labelling or checkweighing equipment.
Which machine type is normally compared for screws, nails and small parts weigh fillers?
Linear weighers, multihead weighers and auger fillers may all be considered depending on product flow, dose size and output target.
Can Lancing help with a complete line rather than a standalone filler?
Yes. Many projects involve product feed, weighing, filling, pack handling, sealing or closing and downstream checking. Sending the full pack route helps avoid choosing a filler that later becomes difficult to integrate.
Send the product, target weight, pack format and output target.
Lancing can advise whether a linear weigher, multihead weigher, auger filler, VFFS line or integrated route is the practical starting point.
Buyer questions
Questions about weighing small parts by count.
Small parts often need a count, a weight, or both. These questions help decide whether a weigh filler route is suitable.
Can screws and small parts be counted by weight?
Yes, where each part has a predictable weight and the agreed count tolerance allows for natural part variation. A representative sample should be weighed and physically counted before the route is confirmed.
How many components are needed for a trial?
The sample should be large enough to test feeder behaviour, discharge and repeatability. A few perfect examples rarely show how parts behave when a hopper is filled from real production boxes.
How is the pack checked after count-by-weight filling?
Common checks include manual count sampling, weight range checks and finished-pack checkweighing. The right method depends on the value of the parts and the buyer’s quality system.
