Keystone KB020TR1D200040 Threaded Rod Tr20x4.0 2m B7

Product Description

The KEYSTONE THREADED PRODUCTS KB020TR1D200040 is a trapezoidal metric threaded rod with a TR20x4.0 thread profile, supplied in a 2-meter length. Manufactured from alloy steel to ASTM Grade B7 specification, this rod features a black oxide finish that provides a baseline level of corrosion resistance for indoor and controlled-environment applications. The ACME-style trapezoidal thread form and right-hand direction make this rod a standard choice for linear motion assemblies, jigs, and structural fastening applications. Licensed tradespeople and mechanical assembly technicians install this type of threaded rod in both fixed and moving load-bearing configurations.

This threaded rod is suited for industrial, commercial, and mechanical applications where a metric trapezoidal thread form is specified. Typical uses include lead screw assemblies, machine frames, conveyor systems, and structural support installations that require a fine-pitch, high-strength threaded element. The single-start thread profile and TR20x4.0 sizing make it appropriate for applications demanding controlled linear travel or consistent axial load transfer.

Key Features

• TR20x4.0 trapezoidal ACME thread profile for linear motion and load-bearing use
• Grade B7 alloy steel construction for high tensile and yield strength
• 2-meter overall length allows field cutting to required dimensions
• Black oxide finish provides surface protection in dry or controlled environments
• Right-hand, single-start thread direction for standard nut and flange compatibility
• Roll-formed metric trapezoidal thread for consistent thread geometry along full length

Compatibility

Designed as an OEM-style replacement or stock component for machinery, structural frames, and linear motion assemblies requiring a TR20x4.0 metric trapezoidal threaded rod in Grade B7 alloy steel.

Installation Notes

Installation is typically performed by millwrights, mechanical contractors, or qualified industrial maintenance technicians. Shut down and de-energize any equipment before removing or installing threaded rod components in powered assemblies. Use appropriate cutting tools and thread chasers when sizing to length to preserve thread integrity at cut ends. Follow applicable mechanical codes and equipment manufacturer specifications for torque and fastener retention requirements.
