Bowl feeding
Dedicated orientation for stable screw, nut and insert geometries.
Application engineering
Fastener, screw & nut feeding systems designed for your production line.
Separate and present screws, nuts, washers, pins, rivets and inserts to automated drivers, presses, robots and assembly stations.
- Machine screws
- Self-tapping screws
- Nuts
- Washers
- Pins
Application overview
How are fasteners, screws & nuts fed automatically?
Fastener feeding must control shank, head, thread and orientation while preventing tangles, doubles and queue lock-up. The final interface may be a precision pick point, escapement, feed tube or insertion tool.
Typical components
Map the full product family before selecting equipment.
Include all variants expected during the project life, not only the easiest or highest-volume component. Even small changes in geometry, material or surface finish can alter flow and orientation.

Feeding methods we would consider.
We confirm the final approach using your production parts and required output.
Step feeding
Useful to assess for longer bolts, pins and components prone to tangling.
Escapement tooling
Separates one fastener at a defined datum for pick-up or transfer.
Engineering risks
Details that determine production reliability.
Tangling and bridging
Long shanks, open features and mixed sizes can create unpredictable bulk behaviour.
Thread protection
Contact surfaces and recirculation should avoid thread damage or contamination.
Tool interface
Blow feed, pick presentation and direct insertion each require different end tooling.
Typical project sequence
From bulk product to controlled presentation.
Verify
Verify the complete fastener family and reject mixed or damaged samples.
Select
Select a bulk and orientation principle that controls tangling.
Establish
Establish head-first, shank-first or pick-face presentation.
Buffer
Buffer the accepted queue without thread interlock.
Singulate
Singulate and confirm one component at the tool interface.
Integration scope
Design the feeder and process machine as one operating sequence.
The technical interface should define discharge datum, available space, machine demand, queue capacity, low-level warning, ready/fault signals, reject handling and operator recovery.
- Mechanical interface drawing and access envelope
- Electrical and controls handshake schedule
- Product recipe and changeover responsibilities
- Factory and site acceptance boundaries
- Documentation, training and spare tooling scope
Application FAQ
Fasteners, screws & nuts feeding questions.
Can screws be blow-fed through a tube?
Suitable screws can be separated and transferred pneumatically, but geometry, length-to-diameter ratio, head shape and required insertion orientation must be assessed.
How are two screws prevented from entering together?
Mechanical escapement geometry, sensors and transfer timing are combined to isolate and confirm one fastener.
Can oily fasteners be fed?
Potentially, but oil changes friction and can contaminate tracks and sensors. The actual production condition should be included in trials and maintenance planning.
Can different screw lengths share one feeder?
Compatible sizes may use adjustable tooling or change parts. The risk of mixed fasteners and incorrect recipe selection should also be addressed.
What samples are required?
Representative fasteners across normal dimensional, finish and supplier variation are preferable to a small batch of visually identical parts.
