I need to mount the boards in the boxes for a finished product.I'm guessing you do to.These are good. ### ⭐⭐⭐⭐⭐ Good sizes for electrical work. *by J***E on April 6, 2024* I purchased these bolts/screws to work on installing plugs and switches. Many times the bolts/screws used on plugs and switches are too short or are lost. These are perfect replacements. I also purchased a kit with longer bolts/screws. Excellent assortment. ### ⭐⭐⭐⭐⭐ More Value Than Expected *by R***T on September 26, 2023* Not only do you get a bazillion 4-40 screws in all lengths, but it’s all squeezed into a small convenient box labeled with the lengths in each compartment. My only gripe is the nuts are packaged separately in a small bag, really no big deal. Definitely worth the money. ## Frequently Bought Together - Guard4U 280Pcs #4-40 UNC Stainless Steel Phillips Pan Head Machine Screws Nuts Assortment Kit- #4-40x 3/16" 1/4" 5/16" 3/8" 1/2" 5/8" 3/4" 7/8" 1" - binifiMux 100pcs 4-40 Nylon Inserted Self Lock Nuts 304 Stainless Steel - HVAZI #2-56 UNC Stainless Steel Phillips Pan Head Machine Screws Nuts Assortment Kit (#2-56UNC) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/295067655-280pcs-4-40-unc-stainless-steel-phillips-pan-head-machine](https://www.desertcart.pl/products/295067655-280pcs-4-40-unc-stainless-steel-phillips-pan-head-machine) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
