ZUFEKMating connection details
Provide both thread interfaces, mounting slots or linkage pins that determine the required geometry.

Assembly and load requirements
Define installation sequence, material condition and required verification for the complete connection.
Repeat-order consistency
Keep drawing revisions, sample decisions, inspection scope and shipment identification aligned.
Choose the connection around installation and load transfer
A stud connecting two threaded parts, a captured slot head and a pin-linked component impose different drawing requirements. Start with the mating interfaces and assembly sequence before choosing a manufacturing route.
| Assembly function | Specify with the mating parts | Acceptance and next review |
|---|---|---|
| Connect different threaded interfaces | Label stud ends A and B with their thread systems, pitches, usable lengths and engagement requirements. Show any shoulder or tool-access feature between them. Custom Double-Ended Studs | Gauge each end against its own specification after the ordered finish. Keep end identification in the inspection and assembly records. Thread Rolling, Cutting & Tapping |
| Capture a head in a mounting slot | Define the actual slot and pocket geometry, head orientation, bearing surface and insertion route. Include the complete clamped stack and tool access. Custom T-Slot Bolts | Trial insertion and tightening in the intended slot. Confirm seating and required anti-rotation without assuming all profile slots share the same section. Multi-Station Cold Heading |
| Join a moving linkage | Show the eye or fork, mating pin, articulation space and load direction. Define the thread engagement and how the joint is retained. Custom Eye & Articulating Bolts | Check the pin interface and movement envelope, then agree any specified joint test. A linkage eye is not automatically an approved lifting attachment. Plan functional tests and records |
Change example: revise a mixed-thread stud
A change at one end can affect how the part is identified and installed even if the other end remains the same. Compare both mating components, shoulder position, tool access and final finish against the revised drawing. List which end-specific gauges and assembly checks must change, and keep the original approval linked to its original revision. Agree the revised sample scope before ordering repeat quantities.
Design-review examples, not customer delivery records. Select the actual limits and checks for the ordered assembly.

Manufacturing and acceptance
For a mixed-thread connection, identify end A and end B on the drawing and inspection plan. If the application involves lifting, provide the approved design and verification requirements separately.
Examples describe application requirements. Material suitability, production scope and verification are confirmed against the approved drawing.

ENGINEERING GUIDE
Eye bolts for linkages and lifting: different specification needs ↗
An eye-shaped end can belong to a linkage, a tensioning device or a lifting component. Similar appearance does not establish the same design requirements or approved use.
ENGINEERING GUIDET-slot bolt fit: what to measure before ordering ↗
A T-head must enter, turn or slide inside the intended slot while retaining the required contact. The slot cross-section is therefore an essential part of the fastener RFQ.
