T Type
Foundation Bolts
Manufacturer
T-head anchor bolts with a transverse bar for wide bearing and high pull-out capacity — ideal for machinery bases and crane rails. M12–M100, welded or forged, MTC certified.
Experience
Trusted T Type Foundation Bolt Manufacturer & Supplier in India
E S Haji & Co. T Type Foundation Bolts manufacturer in India for heavy machinery, steel structures and demanding industrial anchoring since 1994. The T-shaped head (a cross-bar welded or forged at the embedded end) distributes load over a wider bearing area and delivers excellent pull-out resistance in concrete.
Each T bolt is produced to your structural drawing with the head dimension, thread length and embedment specified for the design load. Available M12 to M100, in MS, carbon steel, stainless and high-tensile grades, with Mill Test Certificates and reliable PAN India delivery.
Engineering Behind the T-Head Design: The cross-bar at the embedded end is what sets this bolt family apart — it acts like a flat anchor plate buried in the concrete, converting straight-line pull into a much larger resisting surface. This geometry is why T type bolts are specified wherever vibration, dynamic loading or uplift forces would loosen a standard hex-head anchor over time, including rotating machinery, rail fixings and slotted mounting systems.

What Our Clients Say
We needed forged T-head bolts for a critical press foundation where there was zero margin for error. The single-piece integrity gave our engineering team full confidence, and the bolts have held up perfectly under continuous heavy load.
Sridhar R. Plant Engineer, CoimbatoreOur T-slot channel bolts for the adjustable machine mounts arrived exactly to spec, fitted without any rework, and the finish quality was consistent across the entire batch. This is now our go-to supplier for repeat orders.
Naveen T. Maintenance Manager, HosurThe welded T-head anchor bolts we ordered for our crane gantry rails were delivered well within the promised schedule, complete with proper MTCs for our documentation. Quality and timelines were exactly as committed, with no surprises.

Frequently Asked Questions
Common questions about our T-bolt manufacturing and supply.
-
What is a T type foundation bolt?
A T type foundation bolt has a transverse bar or plate at the embedded end forming a T shape. The cross-bar increases bearing area in concrete, spreading load and giving high resistance to pull-out and rotation. It is used for heavy machinery bases and high-load anchoring.
-
Where are T type bolts typically used?
T type foundation bolts are used for machinery bases, press and turbine foundations, crane rails, slotted base plates and any application requiring wide bearing and high uplift capacity. T-slot variants slide into channels for adjustable positioning.
-
Are T type bolt heads welded or forged?
We supply both. Welded T-heads suit most structural anchoring, while single-piece forged T-heads offer the highest integrity for critical, high-load connections. The choice depends on your design load.
-
What is the minimum order quantity for T type foundation bolts?
We accommodate both bulk industrial orders and smaller project-specific quantities. Minimum order quantity depends on diameter, length and material grade, so share your requirement for an exact quote.
-
What sizes and grades do you offer for T bolts?
We manufacture T type foundation bolts from M12 to M100 in grades 4.6, 5.6, 8.8, 10.9 and 12.9, conforming to ASTM F1554, IS 5624, DIN 529 and ISO 898-1.
-
Do T type bolts come with test certificates?
Yes. Every batch is supplied with Mill Test Certificates (MTCs) confirming material grade, chemistry and mechanical properties.
-
Can you make custom T type bolts to drawing?
Yes. We manufacture T type foundation bolts to your exact head size, thread length, embedment, grade and finish, with reliable PAN India delivery.
-
What is the typical delivery time for T type foundation bolts?
Standard sizes are usually dispatched within a few working days, while fully custom or large-volume orders may take longer depending on specification. We provide a confirmed delivery timeline with every quote.
