Filling out a shopping list in the fasteners springs industrial hardware category can put two very different items side by side. On one hand, you have a box of 1/4"-20 rivet nuts for creating threads in thin metal. On the other, you have a single-cylinder deadbolt for locking a door. The useful decision isn't which is "better" - it's which one matches the job in front of you. This head-to-head sorts out what each product actually does, what it costs, and where it fits.
Quick verdict
If your project needs thread repair or a way to fasten parts to sheet metal, choose the Industrial Grade 100 Pcs Rivet Nut set at USD 10.39. If you're securing a commercial or residential door, choose the Commercial Single Cylinder Deadbolt UH40055 at USD 19.95. The $9.56 price gap reflects two completely different jobs, not two versions of the same tool.

Where each product wins
The rivet nuts win when your task is creating threads in thin metal, repairing a stripped hole, or completing an assembly that needs many fasteners. The knurled texture is designed to grip, and the zinc-plated finish is part of the design. This is the fitting choice for fabrication and repair jobs.
The deadbolt wins when your priority is entryway security. It carries an ANSI Grade 1 rating, includes two keys, and is built for commercial and residential doors. For a complete locking solution, this is the product that protects an opening.
Product notes
1/4"-20 Rivet Nuts
At 100 pieces, this set gives you enough zinc-plated spline-drive inserts to keep working through a multi-panel project or a batch of repairs. The knurled texture is designed to grip metal sheets and pipes, while the flat, deep threads accept standard bolts and screws. The zinc plating adds a protective layer, and the set is described as environmentally friendly, non-toxic, and pollution-free for workshop use. Use them in electromechanical assemblies, automotive panels, railway fittings, furniture, or refrigeration units. That makes them a practical option for projects where you need a threaded attachment point in thin material. The limitation is that these are fasteners-not security hardware. If your shopping list includes locking a door, this box won't help.
Commercial Single Cylinder Deadbolt UH40055
This deadbolt is a complete door-security component. It comes with two keys, installs as a single-cylinder unit, and is rated ANSI Grade 1 for commercial or residential use. The listed backset is 2-3/4 inches, and the assembled dimensions are about 2.5 by 2.5 by 1 inch. That makes it a practical pick when you need to secure an entry door without juggling loose hardware. The limitation is its scope: it won't attach panels, repair stripped threads, or work on sheet metal. It's also listed as new open box, so the package may not be factory-sealed, even though the deadbolt itself is presented as new.
Final choice by use case
Choose the 1/4"-20 rivet nuts when you're working on metal sheets, pipes, or manufacturing assemblies that need reliable threads. Choose the UH40055 deadbolt when you need to secure a door in a commercial or residential space. If both tasks are on your list, buy both-they fill different roles in the same hardware category.
