A button head socket cap screw is a screw with a button head and hexagon drive for tightening with an Allen-style wrench. This screw carries a recessed internal socket drive to add strength. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The button head is round with a low profile, short vertical sides and is suitable for light duty applications. The internal hex drive, also known as a hex-socket drive, has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench. Socket cap screws are threaded fasteners that have a cap head with an internal socket drive for installing in areas with limited side clearance. ## Features - Ideal for use in confined areas where the head needs to be flush or below the surface - Drive Type: Hex Socket; Head Style: Button Head; 18-8 Stainless Steel - Allen Hex Drive Size: 1/16"; Head size: .213" diam, .059" height - Thread: 4-40; inches; 100 Pieces ## Technical Specifications | Specification | Value | |---------------|-------| | Metal | Stainless Steel | | Material Type | 18-8 stainless steel | | Number of Pieces | 100 | | Size | 4-40 x 3/8" | | Head Type | Button | | Screw Head Style | Button | | Fastener Type | button | | Thread Size | #4-40 | | Exterior Finish | Stainless Steel | ## Product Details - **Material:** 18-8 stainless steel - **Thread size:** #4-40 - **Exterior finish:** Stainless Steel - **Head style:** Button - **Fastener type:** button ## Images ![Stainless #4-40 x 3/8" (3/8" to 1-1/2" Available) Socket Button Head Cap Screws, Full Thread, Hex Drive, Stainless Steel 18-8, Machine Thread (4-40 x 3/8") - Image 1](https://m.media-amazon.com/images/I/81GFTElVoRL.jpg) ![Stainless #4-40 x 3/8" (3/8" to 1-1/2" Available) Socket Button Head Cap Screws, Full Thread, Hex Drive, Stainless Steel 18-8, Machine Thread (4-40 x 3/8") - Image 2](https://m.media-amazon.com/images/I/31AKQPChsNL.jpg) ![Stainless #4-40 x 3/8" (3/8" to 1-1/2" Available) Socket Button Head Cap Screws, Full Thread, Hex Drive, Stainless Steel 18-8, Machine Thread (4-40 x 3/8") - Image 3](https://m.media-amazon.com/images/I/81tyvV7uMbL.jpg) ## Available Options This product comes in different **Size Name** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The cutest screw heads *by M***S on Reviewed in the United States on 17 June 2021* You need a very tiny alan key to tighten these, but if you have one lying around, these are great quality screws to fit into a tiny tiny hole. ### ⭐⭐⭐⭐⭐ They are screws. *by J***Y on Reviewed in the United States on 6 May 2022* They hold.
