An installation sheet should tell the installer how to fit the exact product supplied. Generic torque tables are unsafe to transfer between hinge models: the correct tightening method and any torque limit depend on the manufacturer’s instructions for that assembly. If the supplier has not provided model-specific instructions, request them before installation rather than guessing.
Key Takeaways
- Match every instruction sheet to the hinge model and revision being shipped.
- Use the specified glass thickness, cut-outs, gaskets, fasteners and adjustment sequence.
- Do not transfer torque values or anchor instructions from another product.
- Use only tools and installation methods permitted by the manufacturer.
- Keep the approved sheet and revisions with the SKU and shipment records.
Why Product-Specific Instructions Matter
Shower hardware is installed against glass, wall fixings and seals that form one assembly. The installer needs to know which components are supplied, how the parts align and which fasteners are tightened at each step. A catalogue description alone rarely provides enough detail to assemble a particular model consistently.
A torque value, where the manufacturer specifies one, belongs to the exact screw, hinge body, gasket set and assembly it was developed for. Do not apply a value from another hinge or substitute fastener. Wall anchors and glass clamp screws have different installation requirements; follow the relevant product instructions for each.
What to Put on the Installation Sheet
- Product identification: model number, revision, compatible accessories and a parts list.
- Glass fit: approved thickness range, hole or cut-out dimensions, edge requirements and the gasket set for each configuration.
- Mounting information: hinge orientation, opening direction, required support conditions and the wall-anchor type or substrate instructions supplied by the manufacturer.
- Tools and fasteners: sizes, quantities and tool types. State whether powered or impact tools are prohibited or permitted by the product instructions.
- Installation sequence: show the order for positioning, alignment, tightening, adjustment and final inspection.
- Model-specific tightening data: include any torque value and unit only when the manufacturer supplies it for that exact assembly. Identify the tool or method needed to apply it.
- Care and service: explain permitted adjustment, inspection and replacement steps, and identify parts that should not be substituted.
How Buyers Can Review the Instructions
Before approving a supplier, compare the sheet against the product drawing, bill of materials and sample. Check that the model, glass range, cut-out and gasket references agree. Confirm that revisions are controlled when a component or installation method changes.
For installed products, retain the version supplied with each order. If a contractor reports a problem, use the model and revision to compare the installation with the manufacturer’s instructions. Documentation helps reconstruct what was specified; it does not by itself prove the cause of damage or determine warranty liability.

Frequently Asked Questions
What torque should a shower hinge use?
There is no universal torque value for shower hinges. Use the value and method supplied by the manufacturer for the exact hinge, fastener and gasket assembly. If the instructions do not provide one, request written guidance before installation.
Can an installer use an impact driver?
Only if the product instructions expressly allow it. Otherwise use the specified tool and tightening method, because an impact tool may exceed the intended setting.
Should wall-anchor torque match the glass clamp value?
No. They are different connections. Follow the anchor manufacturer’s instructions for the actual anchor and substrate, and follow the hinge manufacturer’s instructions for the glass clamp.
What should be included in a shower hardware installation sheet?
Product identification, compatible glass and cut-outs, the supplied parts, mounting requirements, tools, installation sequence, model-specific tightening data where provided, adjustment steps and revision details.
