1 / 7Insaga INPS-B-4-P2 Weld-On Gate Hinges, Carbon Steel
Insaga INPS-B-4-P2 gate hinges are pre-assembled weld-on hardware with a carbon-steel body, bushings and locking nuts. They suit metal gates where a welded connection is wanted, but the listing’s load figures conflict, so capacity should not be treated as settled.
At a glance
- Pre-assembled, weld-on design is intended to avoid drilling during installation.
- Listing describes steel bushing bearings to reduce friction and locking nuts intended to resist loosening.
- The manufacturer describes use on metal doors, fences, farm gates and driveway gates.

What to know before buying
Listing details to confirm
The listing gives inconsistent load claims: the details state 498.95 kg, while the product description claims 1100 lbs. It also gives different hinge/plate dimensions, including 3.7"x2.8" in the title and 3.7"x1.2" for the welding plate, and describes bearings and a stainless steel dust cover in the description while the feature bullets specify steel bushing bearings. Confirm the exact dimensions, capacity, bearing construction and selected listing before choosing these for a load-critical gate. The stated capacity is not independently verified.

Who is it for?
A good fit for
- Metal gate and door projects where the installer can weld the hinges in place.
- Farm, fence or driveway gates where a compact weld-on hinge is preferred.
Less suited to
- Installations requiring a verified, clearly defined load rating before purchase.
- Gate frames that need a bolt-on or non-weld hinge installation.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller share are one-star and the rating breakdown does not explain why customers chose them. Treat this as a limited indication of overall reception, not evidence of load performance or fit. For buyers weighing a gate, the conflicting capacity claims matter more than the rating pattern.
Frequently asked questions
Are these hinges bolt-on?
The feature description identifies a pre-assembled weld-on design. The listed mounting type is Surface Mount, so the supplied information does not establish a bolt-on option.
What is the stated weight capacity?
The details list 498.95 kg, while the product description claims 1100 lbs. Because these figures conflict, confirm the applicable rating before using the hinges for a heavy gate.
What material and finish are listed?
The listing specifies Carbon Steel and Black Oxide Finish.
