Engineered to meet DIN 912/ISO 898 standards, these screws offer exceptional tensile strength up to 180,000 psi and an internal hex drive for high torque applications, making them ideal for industrial and precision assembly tasks. ## Description Socket Cap Screws are reliable and durable and are used in many applications. They are available in a variety of head styles and materials.Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials.With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. ## Features - Socket Cap Screws are durable and reliable - Alloy Steel is one of the strongest materials used in fasteners, making this an ideal material to use when the primary concern is the application pulling apart - Socket cap head fasteners are very common in industrial applications - Drive system is a hexagon-shaped hole - Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00598DMOO | | Best Sellers Rank | #1,820,527 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #11,951 in Socket Head Screws | | Brand | Small Parts | | Customer Reviews | 3.8 3.8 out of 5 stars (4) | | Drive System | Internal Hex | | Exterior Finish | Black Oxide | | Finish Types | black_oxide | | Global Trade Identification Number | 00082893388465 | | Head Type | Socket | | Item Dimensions | 25 inches | | Manufacturer | Brighton Best | | Material Type | Alloy Steel | | Metal Type | Alloy Steel | | Number Of Items | 100 | | Number of Pieces | 100 | | Part Number | B00598DMOO | | Screw Head Style | Socket | | Set Screw Thread Type | Metric Coarse | | Size Name | M3-0.5 | | Thread Class | 6G | | Thread Coverage | Fully Threaded | | Thread Size | m3-0.5 | | Thread Style | Right Hand | | Thread Type | Metric Coarse | | UPC | 082893388465 | | Unit Count | 100 Count | ## Product Details - **Exterior Finish:** Black Oxide - **Head Style:** Socket - **Item dimensions L x W x H:** 25 inches - **Material:** Alloy Steel - **Thread Size:** m3-0.5 ## Images ![Alloy Steel Socket Cap Screw, Black Oxide Finish, Internal Hex Drive, Meets DIN 912/ISO 898, 25mm Length, Fully Threaded, M3-0.5 Metric Coarse Threads, Imported (Pack of 100) - Image 1](https://m.media-amazon.com/images/I/415Q+MCJNXL.jpg) ![Alloy Steel Socket Cap Screw, Black Oxide Finish, Internal Hex Drive, Meets DIN 912/ISO 898, 25mm Length, Fully Threaded, M3-0.5 Metric Coarse Threads, Imported (Pack of 100) - Image 2](https://m.media-amazon.com/images/I/31J1KCG3h5L.jpg) ![Alloy Steel Socket Cap Screw, Black Oxide Finish, Internal Hex Drive, Meets DIN 912/ISO 898, 25mm Length, Fully Threaded, M3-0.5 Metric Coarse Threads, Imported (Pack of 100) - Image 3](https://m.media-amazon.com/images/I/716dhn9hWNL.jpg) --- ## 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.tw/products/1241334-alloy-steel-socket-cap-screw-black-oxide-finish-internal-hex](https://www.desertcart.tw/products/1241334-alloy-steel-socket-cap-screw-black-oxide-finish-internal-hex) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-24*
