Adjustable Toilet Seat Hinge with PA66+GF Body and 50 mm Base
HSA153ZZ is an adjustable toilet seat hinge with a 50 mm base diameter and a 130–180 mm adjustment range. Its material structure combines a PA66+GF hinge body, SS304 pin cover and LDEP plug nut. M5, M6 and 1/4 in. thread options allow the fixing specification to be selected according to the approved toilet seat and ceramic bowl configuration.
Mixed-Material Structure of HSA153ZZ
HSA153ZZ does not use one material for every hinge component. The material specification should therefore be confirmed by component when the model is added to a toilet-seat BOM or OEM drawing.
The main hinge body uses the specified PA66+GF composite structure. No glass-fiber percentage is stated in the HSA153ZZ specification.
The pin cover is specified in SS304 and should remain identified separately from the PA66+GF hinge body in the approved product specification.
The fixing nut is specified as an LDEP plug. Confirm its dimensions together with the ceramic mounting hole and selected screw thread before order approval.
Material descriptions above follow the HSA153ZZ product specification. Screws and washers are included in the listed component set, but their materials are not specified in the supplied data and should not be assumed.

Check These Dimensions Before Selecting HSA153ZZ
The 130–180 mm adjustment range provides positioning flexibility, but compatibility should be approved from the complete seat, bowl and fixing geometry rather than from hinge-center distance alone.
Fixing-Hole Centers
Measure the ceramic fixing holes center to center. The required hinge position must remain within the 130–180 mm adjustment range after the seat is correctly centered.
50 mm Base Clearance
Check the available mounting area around the rear ceramic fixing points so the 50 mm hinge base can be positioned without interference.
LDEP Plug Fit
Confirm the mounting-hole dimensions and the required plug geometry before approving the fixing configuration. A plug that does not match the ceramic hole cannot provide the intended installation fit.
Screw Thread
Specify M5, M6 or 1/4 in. and approve the matching screw, washer and nut arrangement as one complete fixing set.
Seat-Side Interface
Send the toilet seat drawing or interface dimensions. Correct bowl measurements do not automatically confirm compatibility with the seat-side hinge connection.
Final Seat Alignment
Verify rear clearance, seat centering and final hinge position before freezing the production drawing.
HSA153ZZ Should Be Approved as a Complete Fixing System
Base diameter, adjustment range, plug dimensions, thread specification and seat-side connection all affect the final fit. Approving only one dimension can leave unresolved compatibility issues during assembly.
HSA153ZZ Fit and Order Approval Process
Measure
Record fixing-hole centers, ceramic hole dimensions and the available mounting area around the hinge position.
Match
Check the 50 mm base, 130–180 mm adjustment range and LDEP plug against the intended ceramic bowl.
Configure
Select M5, M6 or 1/4 in. thread and confirm the complete fixing hardware arrangement.
Approve
Verify the assembly with the toilet seat drawing and freeze the approved specification before bulk production.
Salt Spray, Temperature and Supply Specifications
HSA153ZZ has defined test, working-temperature, MOQ and delivery specifications that can be included in the purchasing specification after the final fixing configuration is approved.
NSS identifies the specified neutral salt spray test duration. If your project requires a separate corrosion appearance, cleaning-chemical or market-specific acceptance criterion, define that requirement in the approved purchasing specification.
OEM HSA153ZZ Customization from Customer Drawings
We can customize HSA153ZZ according to customer drawings. For a model-specific toilet seat or private-label program, send the controlled seat and bowl dimensions so the hinge configuration can be reviewed before the order is released.
