8 PCS Adjustable House Floor Jacks 11ft - 16ft Mini Screw Jack

In this review the 8 PCS Adjustable House Floor Jacks are assessed as a straightforward, no-frills solution for temporary leveling and support tasks around the home. Designed for older homes, basements and situations after natural events, these mini screw jacks deliver a single clear benefit: reliable temporary support up to a stated 5000lb per jack using a simple threaded adjustment. For anyone needing to shore up sagging floor joists, porch posts or to stabilize RV steps, this pack is practical and easy to use without heavy equipment or complex installation.

Key Features

• High load capacity: Each jack claims a capacity of up to 5000lb so it can handle heavy localized loads when used as temporary support.
• Adjustable height: The screw adjustment lets users set a precise height between approx 11 in and 16 in by turning the nut until the desired position is reached.
• Durable finish: Galvanized upper parts and black oxide lower parts resist corrosion and extend useful service life in humid or coastal environments.
• Easy to install: Place the jack under the joist or post and use a pipe wrench to raise the threaded shaft, then lock the retaining nut for a fast setup.
• Versatile application: Suitable for floor joists, basement boards, porch supports and stabilizing RV steps or temporary post supports.
• Steel construction: Sturdy steel build provides solid, mechanical support without relying on hydraulic components or complicated tools.

Who It's For

This set is best for homeowners, DIYers and contractors who need a temporary, mechanical way to shore up sagging floors, rotted beams or uneven porches without a full structural rebuild. It fits situations where localized lifting or stabilizing is required and where a simple threaded jack will suffice.

Those who should look elsewhere include projects requiring permanent foundation repair, precision leveling under finished flooring, or lifting beyond the stated travel range; for long-term structural remediation, consult a structural contractor instead of relying solely on these jacks.
