T-Head Bolts Manufacturer for Slot-Based Assembly Systems
Better Fastener Industry Co., Ltd. manufactures T-head Bolts for aluminium profile systems, machine tables, modular fixtures and adjustable structural frames. The T-shaped head slides inside a T-slot channel and locks against the slot walls when tightened from the nut side, creating a repositionable fastening point without dismantling the assembly.
Our range covers standard and custom configurations in carbon steel and stainless steel, produced to DIN 787 and equivalent specifications, with slot widths matched to common profile systems. We supply project quantities with documented material, dimensional and surface-treatment data.
Where T-Head Bolts Fit in the Fastener Range
T-head bolts are one of several bolt families we manufacture. The table below shows how the main bolt types we supply differ in head geometry, clamping behaviour and typical application, so you can confirm the correct family for your assembly.
| Bolt Family | Head / Engagement | Typical Fit |
|---|---|---|
| T-head Bolts | Flat T-head sliding in a T-slot | Aluminium profiles, machine tables, modular fixtures |
| Hexagon Head Bolts | External hexagon, wrench-driven | General structural and machinery joints |
| Hexagon Flange Bolts | Hexagon head with integrated flange | Wider bearing area, reduced need for washers |
| Round Head Bolts (Carriage Bolt) | Domed head with square neck | Timber and low-profile clamping |
| Countersunk Head Bolts | Flush conical head | Flush surfaces, precision assemblies |
| Square Head Bolts | Square head, wrench or spanner | Heavy machinery, timber structures |
| Foundation Bolts | Anchor geometry for concrete | Base plates, structural anchoring |
Slot Compatibility and Head Geometry
The T-head must match the slot profile of the receiving structure. We produce heads to suit standard aluminium profile series and machine table slots, with head width, head length and head thickness controlled so the bolt slides freely when loose and seats firmly against the slot walls under tightening load.
- Head width: sized to the slot opening so the head enters and slides without binding.
- Head length: matched to the slot depth to provide sufficient bearing area.
- Head thickness: controlled to keep the bolt captive in the slot during repositioning.
- Thread length: specified for the clamping stack height and nut engagement.
Materials, Standards and Surface Treatment
We manufacture T-head bolts in carbon steel and stainless steel. Standard production references DIN 787 and equivalent specifications, and we also produce to ASME/ANSI B18.5 where inch-series dimensions are required. Material grade, property class and surface finish are confirmed against the working environment and the mating components.
- Carbon steel: suitable for general industrial and structural use, with zinc plating or blackening as standard finish options.
- Stainless steel: selected for corrosion-sensitive installations, wash-down areas and outdoor exposure.
- Surface treatment: zinc plating and blackening are standard; other finishes are reviewed against the application.
- Thread forms: metric and inch series available, with coarse or fine pitch as specified.
Configuration Options for Project Requirements
T-head bolts are configured around the slot system, the clamping load and the installation method. We review the following variables when preparing a proposal.
Slot and Head
Slot width, head width, head length and head thickness matched to the profile or table.
Thread and Length
Diameter, pitch, thread length and overall length set by the clamping stack and nut engagement.
Material and Finish
Carbon or stainless steel, property class and surface treatment selected for the environment.
Application Fit Across Industrial Sectors
T-head bolts are used where a fastening point must be adjustable along a slot and locked without removing adjacent components. Typical applications include:
- Aluminium profile framing for machine guards, workstations and automation cells.
- Machine table and fixture plate setups where clamps and stops are repositioned.
- Modular exhibition, shelving and architectural systems requiring on-site adjustment.
- Rail, automotive and construction machinery assemblies where slot-based mounting is specified.
Quality Control and Acceptance
Our production follows total quality management with inspection after each process and final inspection of finished products against customer requirements and international standards. An in-house laboratory with spectrometer, CMM, X-ray flaw detector and other testing equipment supports chemical composition, mechanical property, non-destructive and dimensional verification.
- Material certificates and chemical composition records.
- Dimensional inspection reports for head geometry, thread and length.
- Mechanical property testing where the specification requires it.
- Surface treatment verification for plating or blackening.
Information We Use to Configure Your Solution
To prepare a T-head bolt configuration and quotation, we work from the following project inputs. Drawings or samples are the preferred basis for custom production.
| Input | What We Confirm |
|---|---|
| Slot profile or table drawing | Head width, length and thickness |
| Thread size and length | Diameter, pitch, thread length, overall length |
| Material and property class | Steel grade, mechanical properties, standard reference |
| Environment and finish | Zinc plating, blackening or stainless steel selection |
| Quantity and delivery schedule | Batch size, packaging and shipping arrangement |
| Inspection and documentation | Test reports, certificates and acceptance criteria |
Packaging, Delivery and Project Support
We supply T-head bolts in bulk cartons, retail-ready packs or custom boxes according to the sales channel. Our location within a two-hour drive of Shanghai and Ningbo ports supports sea freight as the main mode, with air freight available for urgent deliveries. Trade terms such as FOB and CIF are confirmed at quotation.
Custom production is our core business. We develop and manufacture products based on drawings or samples, and our engineering team supports the transition from prototype to series supply. For standard parts, we also produce a broad range of Bolts and matching Nuts for complete assembly supply.
Frequently Asked Questions
What slot widths can you produce T-head bolts for?
We produce T-head bolts to match standard aluminium profile series and machine table slots, as well as custom slot profiles supplied on drawings. Head width, length and thickness are set to the slot dimensions you provide.
Do you manufacture to DIN 787 and ASME/ANSI B18.5?
Yes. Our T-head bolt production references DIN 787 and equivalent specifications, and we also produce to ASME/ANSI B18.5 for inch-series requirements. The applicable standard is confirmed at quotation.
What materials and finishes are available?
Carbon steel and stainless steel are standard. Zinc plating and blackening are common finish options, with stainless steel grades selected for corrosion-sensitive installations. Material and finish are matched to the working environment.
Can you produce T-head bolts from samples or drawings?
Custom production is our core business. We develop and manufacture products based on the drawings or samples you provide, including non-standard head geometry, thread forms and lengths.
What documentation is supplied with an order?
Documentation is confirmed against the order requirements and can include material certificates, dimensional inspection reports and surface treatment verification. Final inspection is performed on 100% of finished products in accordance with customer requirements and international standards.
How are T-head bolts packaged and shipped?
Packaging is configured for bulk, retail or custom box requirements. Sea freight is the main mode from Shanghai and Ningbo ports, with air freight available for urgent deliveries. Trade terms are confirmed at quotation.
