Review: look very nice going on a 1946 international k100 pickup the right side and left front take right hand threads the left rear takes left hand thread nuts Review: Fit well as a replacement, but the metal seems a little too soft. I installed the wheel back on and tightened them up, but then had to remove the wheel again and re-install. I ended up rounding some of the corners on some of the hex edges, so much so that I could't fit my socket and ratchet on the nut anymore. I tightened them by had but when breaking them free again, corners rounded on 3 of them, luckily, there were 4 more in the pack than I needed for two six lug rims. Definitely should not use an impact wrench on these, because they deformed using a socket and ratchet. I did have to use a short extension to to get the ratchet out beyond the outside of the tire and an extension like that can affect your ability to hold it squarely against the rim which adds more stress on the corners. In my experience, lug nuts need to be made of harder metal than these, but it was a bargain to get 20 for this price. ## Features - Open end acorn design with cone seat - 5/8" total height - Fits vehicles with wheel studs requiring a 1/2"-20 thread and wheels that take a conical 60 degree conical taper - Cr+3 zinc plated steel - Installs with a 13/16" socket ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081THLDT1 | | ASIN | B081THLDT1 | | Brand | BCP Fasteners | | Color | Silver | | Compatible Groove Diameter | 0.5 Inches | | Customer Reviews | 4.6 4.6 out of 5 stars (100) | | Customer reviews | 4.6 4.6 out of 5 stars (100) | | Date First Available | 12 December 2019 | | Drive Style | External Hex | | Exterior Finish | Zinc | | Fastener Type | Hex, Wheel | | Finish Types | Zinc Plated | | Item Weight | 1.14 Pounds | | Item model number | BCP971 | | Manufacturer | BCP Fasteners | | Manufacturer | BCP Fasteners | | Material Type | Steel | | Metal Type | Alloy Steel, Carbon Steel | | Model | BCP971 | | Number Of Items | 20 | | Number of Pieces | 20 | | Part Number | BCP971 | | Screw Head Style | Hex | | Set Name | 20 | | Size Name | 1/2-20 | | Thread Class | Class 2A | | Thread Size | 1/2-20 | | Thread Style | External, UNF, 1/2"-20 | | Thread Type | Unified National Coarse (UNC) | | UPC | 747960015377 | | Unit Count | 20 Count | ## Product Details - **Colour:** Silver - **Exterior finish:** Zinc - **Fastener type:** Hex, Wheel - **Material:** Steel - **Thread size:** 1/2-20 ## Images ![BCP Fasteners Twenty (20) 1/2-20 Zinc Plated Open End Acorn Lug Nuts | 13/16" Hex (BCP971) - Image 1](https://m.media-amazon.com/images/I/81O2qT5-EsL.jpg) ![BCP Fasteners Twenty (20) 1/2-20 Zinc Plated Open End Acorn Lug Nuts | 13/16" Hex (BCP971) - Image 2](https://m.media-amazon.com/images/I/71L+-Ip9SqL.jpg) ![BCP Fasteners Twenty (20) 1/2-20 Zinc Plated Open End Acorn Lug Nuts | 13/16" Hex (BCP971) - Image 3](https://m.media-amazon.com/images/I/7173x-DBKEL.jpg) ![BCP Fasteners Twenty (20) 1/2-20 Zinc Plated Open End Acorn Lug Nuts | 13/16" Hex (BCP971) - Image 4](https://m.media-amazon.com/images/I/61KuRRQ+yTL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***T on 15 April 2026* look very nice going on a 1946 international k100 pickup the right side and left front take right hand threads the left rear takes left hand thread nuts ### ⭐⭐⭐⭐ Review *by R***7 on 31 July 2025* Fit well as a replacement, but the metal seems a little too soft.

I used these on old 1963 AMC wheels that had the stud holes enlarged. The lug nuts that were on it had a 3/4” hex and were sunk very deep into the wheels. These lug nuts, being 13/16” hex had a longer taper due to the larger hex size. Note: Ford wheels are the same bolt pattern but use larger lug nuts. Using these lug nuts with Ford wheels on AMC or Mopar wheels should fix the problem.
