Stainless Steel 304 316 T Bolt Hammer Head Bolt T Head Bolt Hammer Head Screw

This series of products are stainless steel T-type bolts (also known as T-shaped screws, slot screws, aluminum profile-specific bolts), which are specialized fasteners designed for scenarios such as aluminum profile channels, steel structure sliding channels, machine tool guide rails, etc. The products are made with 304/316 stainless steel as the core material, and are formed through multiple processes such as precision cold heading / hot heading, rolling threads, and passivation for rust prevention. The integrated T-shaped head can be directly inserted into the profile channel, and after sliding and positioning, it can be fastened with a nut to achieve quick fixation. They are perfectly suitable for scenarios such as aluminum profile frames, mechanical equipment, and industrial assembly lines, providing a stable, efficient, and rust-proof fastening solution for modular assembly and structural connections.

High-quality stainless steel substrate, with excellent anti-rust and anti-corrosion properties

The core is made of national standard 304/316 austenitic stainless steel, with nickel chromium content meeting standards, non-magnetic, non-toxic and harmless. It has excellent acid and alkali resistance, salt spray resistance, and anti-corrosion properties. It can be used in humid, outdoor, and chemical environments for long-term use. It does not rust or oxidize, and its service life far exceeds that of carbon steel T-type bolts. It complies with food-grade and medical-grade usage standards.

Integrated T-type head structure, convenient and efficient installation in slots

Designed strictly in accordance with GB/T 37 (ISO 186, DIN 186) and aluminum profile industry standards, the T-type head size precisely fits the slot openings of 20/30/40/45/50 series aluminum profiles. After embedding in the slot, it can freely slide and position without the need for additional drilling or welding. It can be directly fastened by matching nuts, perfectly adapting to modular assembly and rapid installation scenarios, without damaging the profile structure.

High-precision rolled threads, tight engagement, anti-loosening, and shock resistance

Using a fully automatic rolled thread process, the thread accuracy reaches 6g grade, with full teeth, no burrs, and no slippage. It has a tight engagement with the same specification nuts/threads, uniform force, excellent anti-loosening and shock resistance performance, capable of withstanding long-term vibration and impact loads, avoiding the risk of loosening and detachment, ensuring long-term stability of the connection; the rolling process also enhances the surface hardness and fatigue resistance of the product, with a service life far exceeding those of cut-off processing bolts.

Multiple specifications and sizes, fully compatible with aluminum profiles

Covering the full range of M5-M16 thread specifications, compatible with all series of industrial aluminum profiles with slot widths of 20/30/40/45/50. The T-type head size precisely matches the slot channels of national and European standard aluminum profiles, no customization required, and direct compatibility is possible. The versatility is maximized.

Solid solution and passivation process, dual excellence in performance and appearance

The product undergoes solid solution heat treatment + rust prevention treatment, eliminating internal stress, optimizing the metallographic structure, and maximizing the anti-corrosion performance and mechanical properties; the surface has high smoothness, no oxide scale, no scratches, a shiny appearance, and enhanced corrosion resistance, reducing stress concentration, and extending the product lifespan.

T-Bolts are widely used in woodworking for furniture assembly, where a countersunk bolt provides a clean, professional look.

Ideal for automotive and machinery applications where a flush mount is necessary to avoid interference with moving parts.

Suitable for outdoor applications such as decks, fencing, and railings, where a combination of strength and weather resistance is needed.
