You're facing a $10 to $20 choice in fasteners, springs, and industrial hardware, but the real fork is the job. Do you need to lock a door or fasten metal parts? The Commercial Single Cylinder Deadbolt UH40055 and the Industrial Grade Rivet Nuts both carry an industrial-duty label, yet they solve completely different problems.
Quick verdict
If the task is securing an entry door, choose the Commercial Single Cylinder Deadbolt UH40055. If the task is assembly work on sheet metal, pipes, or manufacturing projects, choose the Industrial Grade Rivet Nuts. The price spread runs from $10.39 for the rivet nuts to $20.00 for the deadbolt, so the difference in cash outlay is $9.61.
Side-by-side comparison
| Product | Price | Condition | Key details | Best suited for |
|---|---|---|---|---|
| Commercial Single Cylinder Deadbolt UH40055 | $20.00 | New - Open box | 2-3/4 in backset | 2.5 x 2.5 x 1 in assembled | square corner strike | Locking commercial and residential doors |
| Industrial Grade 100 Pcs Rivet Nuts | $10.39 | New | 1/4"-20 UNC thread | 0.25 in groove diameter | zinc-plated | spline drive | Fastening metal sheets, pipes, and assemblies |
Where each wins
The deadbolt wins for access control. It uses a single cylinder, a square corner strike, and a SC1 keyway, and it carries an ANSI Grade 1 security rating plus commercial and residential compatibility. That makes it a strong fit for a busy entry door.
The rivet nuts win for assembly volume. With a full box, a 0.25-inch compatible groove diameter, and a zinc-plated spline drive, they give you a repeatable fastening solution for long manufacturing or repair sessions.
Product notes
Commercial Single Cylinder Deadbolt Universal Hardware UH40055
The UH40055 is a purpose-built lock with a single keyed cylinder and a square corner deadbolt strike. The satin chrome finish, SC1 keyway, and ANSI Grade 1 rating point to commercial door security, and the same lock is also suitable for residential use. With an assembled size of 2.5 x 2.5 x 1 inches and a 2-3/4-inch backset, you have exact numbers to check against your door prep. Its condition is new open-box, so the unit itself is new but the packaging has been opened. Choose it when the job is locking a door. The trade-off is that it is a dedicated locking device: it won't help you fasten sheet metal or join parts.
Industrial Grade 100 Pcs Rivet Nuts
The rivet nut set is the lower-priced option in this head-to-head. The knurled texture, anti-skid performance, and flat, deep threads are meant to make installation straightforward. The zinc-plated exterior and spline drive suit metal sheets, pipes, and manufacturing work, including electromechanical products, automobiles, and furniture. The 0.25-inch compatible groove diameter and 1/4"-20 UNC thread give you a specific size to plan around. Choose it when you need a ready supply of fasteners for repeated assembly tasks. The limitation is that it won't lock a door; it is built for fastening, not entry security.
Final choice by use case
Choose the Commercial Single Cylinder Deadbolt UH40055 when you need one reliable keyed lock for an entry door. Choose the Industrial Grade Rivet Nuts when you need many fasteners for metal assembly. If both jobs are on your list, start with the lower-price rivet nuts to cover the fastening work, then add the deadbolt for the security need. That way, you're matching the hardware to the job instead of forcing one tool to do both.
