Key features

This T-bolt features a rectangular hammer head that can slide directly into C-channel or rail slots without removing the profile end, enabling efficient installation.

The head is integrally forged with high structural strength and stable load capacity, suitable for load-bearing fixing applications.

The surface is blue-white electro-galvanized to form a rust-protective layer, improving corrosion resistance for indoor and regular outdoor environments.

Threads are precision roll-formed with full and complete profile, mating smoothly with matching nuts, providing stable clamping force and resisting thread slipping.

Available in common metric sizes including M6/M8/M10/M12, custom lengths are available to match different channel thicknesses and installation requirements.

Widely used in slot-type fastening systems such as solar brackets, steel structure curtain walls, mechanical pipes, and door/window rails.

The T-head can slide into the slot directly without threading from the profile end, ideal for mounting at intermediate positions on long rails and saving construction time.

Customization of head width, thickness and shank length is available. We can evaluate quotation and lead time upon receiving drawings or samples.

AI-Powered supplier vetting

SummaryThe supplier demonstrates established export experience, with 90% of sales from exports and 22 years of exporting. It has ISO9001:2015 certification, raw-material traceability, quality assurance, and 100% finished-product inspection, although inspection is performed by packing staff and only two quality inspectors are reported. Customization is broad, covering samples, designs, full customization, minor customization, and flexible customization. Service strengths include in-stock capability, stated lead times within 15 workdays in both peak and off-season, and multiple payment and quotation terms. Limitations include no overseas warehouse, showroom, agent, branch, or overseas service-country coverage, no Fortune 500 cooperation, no new products launched in the last year, one R&D engineer, no popular-brand OEM, and an undocumented corrective/preventive-action process. Financial credibility cannot be assessed because the provided financial figures are excluded from evaluation.

Supplier typeThe supplier is strongly export-oriented, reporting 90% export sales and 22 years of export experience. It can provide in-stock service and accepts FOB, CIF, CFR, and EXW terms, but reports no overseas warehouse, showroom, agent, branch, or overseas service-country coverage.

CertificationsThe supplier reports an ISO9001:2015 certificate for both sustainable development management and management systems, plus other product compliance or sustainability certifications. The specific additional certifications are not identified, so the evidence supports ISO9001 holding but not broader certification strength.

R&D capabilityThe supplier reports one R&D engineer and no new products launched during the previous year. It also reports no available SDK and no popular-brand OEM capability, which indicates limited documented innovation evidence.

Production capacityProduction-related evidence includes raw-material traceability, 100% finished-product inspection, quality assurance, four own-brand quality-control capabilities, inventory capacity, and lead times within 15 workdays in both peak and off-season. Only two quality inspectors are reported, and finished products are checked by packing staff, so production capability is positive but quality-control depth is limited.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.

Product Q&A

Q:Serrated T bolt vs square neck T bolt - which has better anti-rotation?

- Machine tool steel T-slots, heavy-duty fixtures, applications requiring repeated assembly and disassembly, and high-torque tightening - Choose square-neck T-bolts for more stable anti-rotation performance. - Aluminum profile frames, subject to continuous vibration, requiring both anti-rotation and prevention of bolt slippage along the slot - Choose serrated T-bolts.

Q:Fine thread vs coarse thread T bolt - which is better for high-vibration?

Fine-pitch threads offer better self-locking performance and are less likely to loosen under lateral vibration; however, coarse-pitch threads are more tolerant of misalignment and are better suited for applications involving dust, shock, and aluminum extrusion threads.

Q:T bolt (DIN 186) vs T-slot bolt (DIN 787) vs hammer head bolt -- which type do I need?

DIN 186 / DIN 787 are designed specifically for steel T-slots (DIN 649/DIN 650) on cast-iron machine tool tables; hammer-head bolts are designed specifically for T-slots in industrial aluminum profiles.
