Product Description

Product Overview

This product is a T-bolt (hammer head bolt) consisting of a T-shaped rectangular head and a threaded shank, manufactured from high-quality carbon steel with a yellow zinc plating. The T-shaped head slides into the T-slot of a workpiece or worktable and locks in place after a 90-degree rotation, and can slide freely along the slot to adjust the mounting position, providing fast clamping and flexible adjustment. Most of the shank is covered with precision threads, while a smooth unthreaded section is retained near the head for smooth entry into the slot and easy assembly. With a uniform golden surface and good corrosion resistance, it is a common fastening and connection component for machine tools, fixtures and various T-slot structures.

Product Features

Fast positioning T-head: The T-shaped head slides into the T-slot and locks with a 90-degree rotation, providing fast clamping and reliable positioning without additional retaining parts.

Free adjustment in the slot: The bolt can slide along the T-slot to any required position before being locked, adapting to flexible tooling and assembly requirements.

Precision threaded shank: The threads are clearly formed, uniform and complete, ensuring smooth engagement and reliable locking for strong connections.

Smooth unthreaded section: The unthreaded section below the head allows the T-head to slide smoothly into the slot and reduces stress concentration for higher shank strength.

Yellow zinc plating protection: The high-quality carbon steel base is finished with a yellow zinc plating, giving a uniform golden surface with good rust and corrosion resistance for workshop and outdoor environments.

Application Field

This product is widely used for fastening and quick clamping in various T-slot structures, including machine tool worktables and fixture platforms, industrial aluminum profile frames, steel channel and structural connections, machinery and conveyor systems, and inspection jigs. It is especially suitable for applications requiring repeated clamping and frequent position adjustment.

Instructions for use

Selection: Choose the appropriate T-bolt according to the slot width and specification of the T-slot, the thickness of the connected parts and the load requirements, and check that the threads and head are in good condition.

Inserting into the slot: Slide the T-shaped head into the slot from the end of the T-slot, or insert it from the opening and rotate it to the locking direction so that the head seats against the bottom of the slot.

Assembly and tightening: Place the workpiece or clamp plate over the bolt, slide on a washer and thread on a hex nut, then tighten with a wrench to the specified torque so that the T-head is firmly locked in the slot.

Inspection: After tightening, confirm the head is correctly seated and the connection is firm. To adjust the position, loosen the nut, slide the bolt to the new position and re-tighten.

Maintenance

Dry storage: Store unused bolts in a dry and ventilated place to prevent rusting after coating damage.

Periodic inspection: For connections under long-term load or in vibrating environments, check regularly for loosening or corrosion and re-tighten or replace in time.

Cleaning: Clean chips, oil and dirt from the T-slot and threads regularly to ensure smooth sliding and reliable engagement.

Proper use: Always use bolts matching the T-slot specification, avoid slots of mismatched width, and never reuse parts with damaged or deformed threads.

FAQ

Q: What material and surface finish does this bolt have?

A: It is made of high-quality carbon steel with a yellow zinc plating, giving a uniform golden surface with good rust and corrosion resistance. The specific material and plating process are subject to the product specification.

Q: What is the function of the T-shaped head?

A: The T-shaped head slides into the T-slot and locks with a 90-degree rotation, allowing the bolt to be tightened without holding from the back side and to slide along the slot for position adjustment — fast and flexible clamping.

Q: Why is there an unthreaded section on the shank?

A: The unthreaded section below the head allows the T-head to slide smoothly into the slot and through the workpiece, while reducing stress concentration for higher shank strength.

Q: How to select the right specification?

A: Choose the diameter and length according to the T-slot width specification, the thickness of the connected parts and the load requirements. Provide your slot parameters for sizing assistance.

Q: How to prevent loosening and rust?

A: Tighten the nut to the specified torque, re-tighten periodically or use lock washers in vibrating environments, avoid scratches on the yellow zinc surface, and inspect regularly during long-term use.
