1. Flexible Positioning & Easy Installation
The T‑head design allows insertion into T‑slots at any location without needing to slide from the end of the profile. After insertion, a simple quarter‑turn locks the bolt in place, preventing rotation during tightening. This feature dramatically reduces assembly time compared to traditional slide‑in nuts, especially on long conveyor frames where accessing the slot end is difficult.
2. Secure & Vibration‑Resistant Connection
When torqued, the T‑head seats against the internal faces of the T‑slot, providing a strong, anti‑rotation grip. This ensures mounted components remain stable even under conveyor vibration or dynamic loads. Serrated or toothed variants are available for enhanced locking. The bolt’s thread engagement supports high clamping forces without stripping the aluminum profile groove.
3. Multiple Materials & Finishes for Harsh Environments
Zinc‑plated carbon steel T‑slot bolts offer cost‑effective general purpose use. Stainless steel versions provide excellent corrosion resistance for washdown areas, food processing, pharmaceutical lines, and outdoor conveyors. For highly corrosive or chemical‑exposed environments, nylon‑coated or full stainless steel (SUS316) grades are recommended. All options maintain consistent thread precision and T‑head dimensional accuracy.
Product Uses
1. Conveyor Side Guide & Guard Mounting
T‑slot bolts are widely used to attach side guide rails, wear strips, and protective covers to T‑slotted aluminum conveyor beams. By loosening the bolt, operators can quickly reposition guides for different product widths or replace worn components without drilling or welding. Stainless steel bolts are preferred in food and beverage lines requiring frequent washdown.
2. Sensor & Bracket Fixing on Assembly Lines
Automated production lines rely on T‑slot bolts to mount photoelectric sensors, proximity switches, and pneumatic valve brackets onto profile frames. The ability to slide the bolt along the T‑slot allows fine‑tuning of sensor positions for optimal detection. Reconfiguration between product changeovers takes minutes rather than hours.
3. Lean Manufacturing Workstations & Machine Guards
In assembly cells, ergonomic workstations, and machine guarding systems, T‑slot bolts connect crossbars, shelving, panel mounts, and hinged doors to extruded profile structures. Their reusable nature supports continuous layout improvements and rapid prototyping of custom fixtures. Combined with T‑nuts and corner brackets, they form a complete modular framing solution.










The T-Slot Bolt is a fastening component designed for use with T-slotted aluminum extrusion profiles, conveyor support frames, and modular assembly structures. The bolt head features an inverted T shape that inserts into profile slots at any accessible point and rotates 90 degrees to lock into position. T-slot bolts are manufactured in carbon steel with zinc plating, or stainless steel grades including SUS304 and SUS316 for different environmental requirements. Thread sizes range from M6 to M8 for flexible chain conveyor applications, with compatibility for standard nuts and washers. These bolts serve as adjustable connection points for mounting guide rails, sensors, brackets, and other modular accessories on conveyor lines and assembly workstations.

Standard inventory includes M6 and M8 thread sizes for flexible chain conveyor applications. Other thread dimensions can be produced for volume orders. All bolts follow standard metric thread tolerances for compatibility with common nuts and washers.
Zinc-plated carbon steel bolts are intended for dry indoor use. For outdoor installations, washdown areas, or humid environments, select SUS304 or SUS316 stainless steel variants, which provide corrosion resistance without additional coating.
T-slot bolts and accessory fasteners are packaged in standard cardboard boxes, with quantities based on order volume. Small accessory orders typically ship within 3 to 5 business days after confirmation, while larger volume orders require 5 to 7 business days. All lead times refer to business days and exclude public holidays.
