Review: T-nut - What I have found out, the knock offs, some are just ok at best, if your going to use a Magpul M-lok system use oem hardware, such better quality and guaranteed fit. Review: Magpul! - I don’t often care to spend the extra cash on something so trivial as nuts and bolts. And you can literally buy a generic pack of these for like 20 for $5. But, if you have an mlok rail without a lot of space, and try to mount anything near the gas block, you’ll realize quick that them generic, skinny, long bolts won’t work. So, I ordered these as they came with 2 separate length bolts. And lo and behold, they are like TWICE the diameter of them crappy generic mlok bolts. These things are BEEFY! And the short ones didn’t touch my gas block, deflecting my barrel. I bought a few packages as all my magpul items come with them (barrier stop), so I kinda had some first hand knowledge of these fatties!! Just wanted yall to know too!! They come pre threadlocked, and ready to rock. This is an item I refuse to go generic on!!! They hold my $400 cloud rein!!! They hold my $130 vertical grip! They hold my mlok pressure pad mount!! This $5 holds almost $1000 worth of items on my rail. And at only $5….why go cheaper!?!? ## Features - Replacement hardware pack designed for Use with all M-LOK accessories - Made of 4140 chromoly steel with a Mil-Spec manganese phosphate finish - Supplied with two T-Nuts as well as two different length button-head cap screws to ensure compatibility with various hand guard or forend thicknesses - A self-locking reusable thread patch is added to the screws to ensure a secure fit upon installation - Made in USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PDKOC4W | | Best Sellers Rank | #46,573 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #108 in Hunting & Shooting Gun Stock Accessories | | Brand | Magpul | | Color | Black | | Customer Reviews | 4.7 out of 5 stars 1,358 Reviews | | Exterior Finish | Steel | | Fastener Type | Tee | | Finish Type | Manganese Phosphate | | Finish Types | Manganese Phosphate | | Global Trade Identification Number | 00873750004082 | | Grade Rating | Mil-Spec | | Included Components | M-LOK T-Nut Replacement Set | | Inside Thread Size | M8 | | Item Dimensions | 0.51 x 4.25 x 0.98 inches | | Item Type Name | M-LOK T-Nut Replacement Set | | Item Weight | 27.22 g | | Manufacturer | Magpul Industries Corp. | | Material | 4140 Chromoly Steel | | Material Type | 4140 Chromoly Steel | | Maximum Shear Strength | 580 MPa (84,000 psi) | | Metal Type | Alloy Steel | | Model | MAG615-BLK | | Number Of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 4 | | Part Number | MAG615-BLK | | Screw Head Style | Button | | Set Name | Magpul M-LOK T-Nut Replacement Set | | Size Name | One Size | | Thread Class | M-LOK | | Thread Coverage | Fully Threaded | | Thread Style | Socket Head Cap Screw ( Allen ) | | Thread Type | M6 X 1.0 Metric | | UPC | 873750004082 | | Unit Count | 1 Count | | Warranty Description | 2 Year Manufacturer | ## Product Details - **Color:** Black - **Exterior Finish:** Steel - **Fastener Type:** Tee - **Material:** 4140 Chromoly Steel - **Metal Type:** Alloy Steel ## Images ![Magpul M-LOK T-Nut Replacement Set - Image 1](https://m.media-amazon.com/images/I/41FYKcHQgaL.jpg) ![Magpul M-LOK T-Nut Replacement Set - Image 2](https://m.media-amazon.com/images/I/51aslVsogsL.jpg) ![Magpul M-LOK T-Nut Replacement Set - Image 3](https://m.media-amazon.com/images/I/51xPK7tONjL.jpg) ![Magpul M-LOK T-Nut Replacement Set - Image 4](https://m.media-amazon.com/images/I/71tdVU5Rt-L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: How long are the screws?** A: I called Magpul and asked the same question.
