Product Description

M5 M6 Stainless Steel SUS304 SUS316 Serrated Hexagon Head Flange Metal Bolt DIN6921

Description

Flange bolt is composed of hexagonal head and flange, with a "support area and stress area ratio" greater than ordinary bolts. This design enables higher preload capacity and superior anti-loosening performance, making it ideal for automotive engines and heavy machinery applications.

The flange bolt consists of:

Hexagon head with integrated flange (gasket fixed to hexagon)
Screw with external threads

Surface finishes: Plated white, army green, color yellow, corrosion resistant Dacromet

Flange types: Various sizes available for different applications

Used with nuts to fasten parts connecting two through holes, creating a detachable connection.

Hexagonal head types: Flat head or concave head

Applications

Automotive	High-strength applications including engines and transmissions, valued for larger support area and anti-loosening properties
Mechanical	Connecting mechanical parts in electronics, construction, and industrial equipment
Energy	Brackets and fixtures for power generation equipment and transmission lines
Architectural	Building structures, shipbuilding, and petrochemical equipment for enhanced safety and stability

Material Specifications

Aluminum	Excellent thermal/electrical conductivity but soft; requires careful processing to avoid buildup
Titanium	Requires EDM machining with deionized water to control heat during processing
Steel	Very strong; often processed with wire cutting machines for complex features
Brass	High tensile strength but requires slow cutting speeds due to softness

Feature Advantages

Thinner flange design allows slight deformation for more secure locking compared to ordinary bolts
Can be used with special tools in confined spaces where ordinary bolts cannot be accessed
Flange plate provides additional fastening surface area
Safer for softer materials as flange distributes load and prevents perforation

High-carbon steels (C: >0.6%) are classified as tool steels, containing 0.60% to 1.70% carbon for hardening and tempering. Applications include hammers (0.75% carbon) and cutting tools (0.90-1.00% carbon).
