DIN 6331 Hex Nut With Collar Height
DIN 6331 Hex Nut With Collar Height
Hex nut with collar height refers to a type of hexagonal-shaped nut that is designed with an additional collar feature that extends beyond the standard height of the nut. This collar helps to distribute pressure evenly across the surface area of the nut, helping to prevent damage or deformation to the materials being secured. By extending the height of the nut, the added collar provides extra support and helps to maintain a secure, tight fit.
Description
Product Information
Hex flange nuts are a type of fastener with a hexagonal-shaped flange at their base. These nuts are designed to be used in situations where the fastened joint requires a greater degree of security, such as in automotive or industrial applications. The flange helps to distribute the load across a broader surface area, reducing the likelihood of the nut loosening over time. Additionally, hex flange nuts often feature a serrated face on their underside, which provides extra grip on the material being fastened. These nuts are commonly made from steel, although other materials such as brass or stainless steel can be used depending on the application.

Common Bolt Materials
Bolts and nuts are fabricated from a variety of materials. These options include metals and polymers. Stainless steel offers strength and corrosion resistance. While polymer options have less strength than stainless, they are a good choice for resisting chemicals. The most common materials are:
- Stainless steel
- Alloy steel
- Low carbon steel
- Medium carbon steel
- Titanium
- Polymers, such as nylon
Finish Options
The use of heat treatments and application of various finishes, also known as “plating,” affects the look and performance of nuts and bolts. Finishes provide material stability and protect the fasteners from corrosion and rust. Below are some common heat treatment and finish benefits:
- Zinc coating – Most common, low cost, resists corrosion and rust
- Galvanized – Superior corrosion protection, anti-seize, higher upfront investment
- Stainless – Great for humid environments, strong, ideal for electrical or mechanical uses
- Black – Adds color, provides better grip, deflects light

FAQ
Q: What is the function of a nut?
A: A nut is a mechanical fastener with a threaded hole. It is attached to a bolt, screw or stud to provide a clamping force and prevent axial movement.
Q: Do screws have nuts?
A: Screws don’t need nuts, as they become secure by being tightened into the hole with a screwdriver or driver bit which fits into the drive recess. Generally speaking, screws are shorter than the width of the material they are being screwed into, so that they don’t protrude on to the other side.
Q: What is the difference between a lock nut and a hex nut?
A: The term “Lock Nut” is used to describe a nut that is designed to provide higher resistance to loosening as compared to a standard hex nut. Lock Nuts are commonly used in applications that encounter vibration or impact forces that can cause a standard nut to loosen over time.
Q: What is the difference between a square nut and a hex nut?
A: Hex nuts are easier to install and tighten than square nuts. They have six sides, whereas square nuts only have four sides. Because they have more sides, hex nuts offer more torque, which makes them easier to install and tighten. You can install hex nuts in smaller spaces.
Q: What is a DIN 934 nut?
A: Din 934 is the standard for Hexagon nuts with metric coarse and fine pitch thread – There are two product classes A (up to M16) and B (> M16) DIN stands for “Deutsches Institut für Normung”, meaning “German institute for standardisation” and is widely accepted globally, though many are not superseded by ISO standards.
Q: What is the ASTM standard for hex nuts?
A: Hex nuts (also referred to as finished hex nuts) are available in ASTM A563-A and compatible with low carbon steel bolts such as ASTM A307, ASTM F1554 grade 36, SAE grade 2, and AASHTO M183.
Q: What is DIN 936?
A: DIN 936 hex nuts are jam nuts, it has a fine thread.
Q: What is flange nut as per DIN 6923?
A: DIN 6923 ISO 4161 Serrated Flange Nut are hex nuts with non-spinning washers attached at the bottom. Below the washers are serrations which prevent them from being used with washers or on surfaces that can be scratched and help the nuts to securely fasten when vibrations are present.
Q: What is DIN 985?
A: DIN 985 Nylon Insert Hex Lock Nuts are internally machine screw threaded hex nuts that rely upon an undersized captive nylon (polyamide) washer to create the prevailing torque feature that resists rotation and, hence, loosening.
Q: What is DIN 6926?
A: Metric DIN 6926 Nylon Insert Hexagon Flange Lock Nuts have a circular washer like flange shaped base that increases the. weight bearing surface to distribute the load over a greater area when tightened The flange eliminates the need to use a washer. with the nut.
Q: What is DIN 980?
A: DIN 980 lock nuts, all metal lock nut is also known as all metal self-locking nut. There are two main locking forms:
a. This kind of nut is called 980-v type, and the common forms are as follows: end face three-point type, elliptical type, side extrusion type.
b. The nut is embedded with a metal locking plate, which can prevent loosing by the locking ring. This kind of nut is called 980-m
Material: Carbon Steel
Type: All metal prevailing Torque, Hex Nuts
Thread Size: M3 ~ M39
Surface Finish: Plain, Black, Zinc Plated, Yellow Plated, H.D.G, Chrome Plated
Class: 4, 6, 8, 10
Q: What is the din standard for square nuts?
A: Square nuts, DIN 557.
Q: What is DIN 562?
A: DIN 562 – Square thin nuts.
Q: What is DIN 929?
A: Hexagon weld nuts.Three uniform projections ensure reliable contact with the weld surface, even if it is not perfectly flat. The precision pilot accurately locates the threads in the pilot hole and prevents the nut from slipping off center during welding.
