Technical Specifications, Customization, Quality Control & Bulk Supply
Designed for Point-Fixed Glazing Applications | Drawing-Based Customization | Project-Specific Material and Dimensional Verification
Product Overview & Selection Essentials
Glass Compatibility: Confirm glass thickness, hole diameter, countersunk angle, recess depth, and edge distance against approved glass fabrication drawings.
Connection Compatibility: Verify the fixing dimensions, thread size, engagement length, and mating geometry with the designated spider fitting.
Material Selection: Specify the stainless steel grade and surface finish according to the installation environment and project requirements.
Engineering Documentation: Confirm available material certificates, dimensional inspection records, and required product or assembly validation documents before order approval.

Product Configurations
Fixed Countersunk Glass Fixing: For assemblies requiring a fixed connection geometry, subject to the approved design and component specifications.
Articulated Countersunk Glass Fixing: For assemblies designed to permit a specified degree of angular movement. Permitted movement and load requirements must be verified for the complete connection system.
Important Selection Note: Glass thickness alone does not establish compatibility. The glass recess, hole geometry, edge distance, fixing dimensions, installation requirements, and structural design must be assessed together.
Key Features & Application Fit
Countersunk Head Design: The head geometry is intended to sit flush with or below the glass surface when the glass recess and fixing are correctly matched. The final position depends on the specified dimensions and installation tolerances.
Connection Interface Compatibility: Thread specifications, engagement length, and mating geometry must match the designated spider fitting and approved assembly drawings.
Gasket and Isolation Components: Specified gaskets or bushings may be used to separate component interfaces or provide designated contact functions. Their material and performance requirements should be confirmed for the assembly.
Typical Applications: Point-fixed glass curtain walls, structural glass facades, glass fins, and glass canopies, where the selected component is approved for the relevant system.
Customization, Manufacturing & Quality Control
OEM / ODM Customization
Drawing-Based Production: Custom dimensions and interfaces can be reviewed against customer-supplied 2D or 3D drawings, subject to manufacturing capability and technical approval.
Configuration Options: Potential customization includes head diameter, countersunk angle, thread size, stud length, material grade, and surface finish.
Sample Approval: Where available, pre-production samples can be used to verify dimensional compatibility and assembly fit before batch production.
Required Technical Files: Provide dimensioned PDF drawings or compatible CAD files, such as DWG or STEP, together with the required material and finish specifications.

Bulk Supply, Packaging & Order Planning
Protective Packaging: Individual component protection and separation can be specified to help prevent scratching and contact damage during handling and transit.
Batch Identification: Labels may include part numbers, order references, and batch identifiers according to the agreed traceability requirements.
Export Packaging: Inner cartons, master cartons, and palletized packaging can be specified according to shipment quantity, component dimensions, and transport requirements.
Mixed-Model Orders: Provide an itemized schedule identifying each model, material grade, finish, quantity, and drawing revision to reduce specification discrepancies during order processing.
Frequently Asked Questions
Q: What information is needed to select a countersunk glass spider fixing?
A: Provide the glass thickness, hole diameter, countersunk angle and depth, edge distance, fixing dimensions, thread specification, and spider fitting drawing. The complete assembly should be checked before order confirmation.
Q: How do I choose between fixed and articulated configurations?
A: The choice depends on the connection design and whether controlled angular movement is required. Confirm the permitted movement, load conditions, and interface requirements with the project engineer.
Q: Should I specify stainless steel 304 or 316/316L?
A: The appropriate grade depends on environmental exposure, corrosion requirements, material specifications, and the project design. Coastal or chloride-exposed installations require particular attention to corrosion assessment. Confirm the required grade with the responsible designer.
Q: Can the countersunk geometry and thread be customized?
A: Customization may be possible for head dimensions, recess geometry, thread specifications, and mounting interfaces, subject to manufacturing capability and approved drawings.
Q: What quality documents can be supplied?
A: Available documentation should be confirmed before ordering. Depending on the agreed specification, this may include material certificates, dimensional inspection records, batch identification records, and a Certificate of Conformity. EN 10204 Type 3.1 certification should be explicitly agreed where required.
Q: What should I include in a bulk quotation request?
A: Provide technical drawings, glass preparation details, material and finish requirements, quantities by model, required documentation, destination, and target delivery date. Include any project-specific testing or inspection requirements.
