What Stands Out
Product Details
- HIGH QUALITY MATERIAL: This release knob is made of high quality aluminium, high hardness, strong bearing capacity, not easy to deform, and the surface is corrosion-resistant, long service life.
- UNIQUE DESIGN: This jack release knob can perfectly replace the jack handle lever. No need to disassemble the jack handle on the plunger/pivot assembly to release the jack every time.
- EASY TO GRIP: The knob has a printed surface for better feel and grip. Friction is also good for preventing slippage caused by sweaty hands.
- EASY TO INSTALL: Slide the jack valve knob onto the jack release screw and turn 1/4 turn to snap it into place. Then use a 5/32 hex spanner to install the set screw to the end of the knob and tighten for security.
- COMPATIBILITY: Can be used on 6, 12 and 20 tonne presses as well as any bottle jack with a 7/16 inch diameter as a pressure release knob.

STPCTOU Accessories QJD Editorial Review
The Hydraulic Press Jack Valve Screws, featuring a 3/8" Bottle Jack Valve Release Knob, have garnered attention for their usability and quality among customers who use them in conjunction with Harbor Freight hydraulic jacks. Customers have reported positive experiences, frequently highlighting the ease of installation and practical enhancements to operation. Made from 6061 aluminum, this product is praised for its strength and durability, providing a reliable replacement for often-worn jack handles. Users appreciate that the knob allows for more convenient operation compared to using the traditional jack handle. This upgrade improves not only functionality but also the overall user experience. One customer emphasized that installing the knob significantly simplified the clunky manual jacking process, making it an essential tool for those working on hydraulic presses and bottle jacks. The knob's design is user-friendly, allowing for a straightforward installation that doesn't require professional expertise or special tools. However, there are some limitations noted by a few customers.

Some users also reported that they wished for greater grip enhancement, indicating that a slightly deeper knurling would improve the user experience further. A few concerns about quality control were brought up, with some customers receiving knobs that did not fit properly on certain hydraulic valves, suggesting possible inConsistencies in manufacturing. In summation, the Hydraulic Press Jack Valve Screws are well-received by customers for their Construction and effectiveness, making them a worthwhile investment for enhancing the functionality of Harbor Freight hydraulic jacks. **
