Indented & Undercut Hex Flange Screws
Valley Fasteners is a leading supplier of industrial-grade fasteners to automotive, construction, manufacturing, and industrial companies. With over 45 years of experience, our team can design and manufacture diverse custom fasteners, including indented hex flange screws for commercial and industrial applications.
Features of Undercut Hex Flange Screws
Indented and undercut hex flange screws feature a hexagonal head and integrated flange. An undercut design helps improve grip and functionality. They are ideal for many industrial and commercial applications in construction, heavy equipment, and automotive manufacturing.
The integrated flange eliminated the need for a separate washer. This increases efficiency in high-volume operations, such as assembly lines. Screws with a serrated flange have increased grip, which helps to reduce slipping that can occur from high vibrations.
A hex head further increases the security of connections made with indented hex flange screws. The shape can easily accommodate high torque levels without stripping or cam out common with recessed head styles.
Custom Undercut and Indented Hex Flange Screw Capabilities
VFG works with a range of metals to produce high-quality fasteners. Common materials include:
- Aluminum
- Low carbon steel alloy
- Medium carbon steel alloy
- Stainless Steel
Stainless steel and aluminum offer excellent corrosion resistance in high-moisture environments or applications with chemical contact. Steel alloys are cost-effective solutions for general-purpose uses. Medium-carbon steel alloys are durable and suitable for structural applications. We offer multiple finishes, including galvanized, oiled, and zinc-plated.
Thread Profiles
We can manufacture undercut hex flange screws in UNC, UNF, and metric thread patterns. Unified coarse threads help counter moderate vibration and provide fast assembly. They are somewhat prone to cross-threading. Unified fine threads provide a higher degree of protection against vibrations and may be a good choice for many undercut flange bolts.
Commercial and Industrial Applications
Undercut hex flange screws have many uses in automotive manufacturing, aerospace, construction, and energy sectors. They are widely used to secure:
- Automotive body panels, frames, and components subject to heavy vibrations
- Ductwork and mounting brackets in HVAC systems and solar panel mounts
- Heavy-duty equipment installation and structural steel framing connections
- Manufacturing and industrial equipment
- Major laundry and kitchen appliances
- Packaging and material handling equipment
- Pipelines in rigs and refineries
Because they provide secure connections that resist vibrations, they are also well-suited for moving parts in many other manufacturing areas, including assembly lines, conveyors, and palletizers.
