It features the following characteristics: The top is dome-shaped or closed, unlike standard nuts which have an open hole; one end is sealed. The product resembles a small cap. It still has internal threads and can be screwed onto a bolt just like a standard nut. https://www.chinaboltnut.com/uploads/47632/video/202607011913387e2f3.mp4 2026-04-30T09:11:08+08:00 yes no https://www.chinaboltnut.com/bolts/socket-head-cap-screws/din-912-class-4-8-socket-head-cap-screw.html https://www.chinaboltnut.com/uploads/47632/small/din-912-class-4-8-socket-head-cap-screw2026043009312094951.jpg DIN 912 Class 4.8 Socket Head Cap Screw ● Product Name: DIN 912 Hexagon Socket Head Cap Screw (Grade 4.8), commonly known as a cup-head screw or hexagon socket screw ● Standards: German Industrial Standard DIN 912 (equivalent to International Standard ISO 4762 and Chinese National Standard GB/T 70.1) ● Strength Grade: Grade 4.8 (Standard carbon steel base grade, nominal tensile strength 400 MPa, yield strength 320 MPa) ● Material: High-quality medium- and low-carbon steel (Q235, 35# steel) ● Surface Treatment: Blackening (oxidation), zinc plating (blue-white zinc / colored zinc), hot-dip galvanizing, etc. (customizable) ● Product Features: Cylindrical head + internal hex socket; requires an internal hex wrench for installation https://www.chinaboltnut.com/uploads/47632/video/202607011915506dd35.mp4 2026-04-30T09:37:08+08:00 yes no https://www.chinaboltnut.com/bolts/hex-head-bolts/din-933-class-4-8-zinc-plated-hex-bolt.html https://www.chinaboltnut.com/uploads/47632/page/small/din-933-class-4-8-zinc-plated-hex-bolt56a8b.jpg DIN 933 Class 4.8 Zinc Plated Hex Bolt DIN 933 class 4.8 zinc plated hex bolts are manufactured in strict compliance with German industrial standards.
