Insert Nut Semi Hex Reduced Head

Yellow Enterprises, presents the Insert Nut Semi Hex Reduced Head in premium stainless steel. Offering a semi-hexagonal body to prevent rotation and a reduced-profile head for flush installation, this fastener ensures robust threaded connections even in thin or space-critical materials. Ideal for automotive, electronics and metal-fabrication applications.

Yellow Enterprises, established in 2017 in Pune, Maharashtra, India, is a specialist manufacturer of stainless steel blind self clinch nuts and other advanced fastening solutions. Our new product, the Insert Nut Semi Hex Reduced Head, exemplifies our commitment to precision engineering, quality materials and optimal performance in demanding applications.

The Insert Nut Semi Hex Reduced Head is a purpose-designed threaded insert in which the body features a semi-hexagonal (half-hex) profile, coupled with a reduced-head design that allows for a low-profile or flush mounting. This combination delivers key benefits: anti-rotation under torque, minimal protrusion, and high reliability in sheet-metal, thin-wall or restricted-space assemblies.

Key Features & Benefits

Semi-hex body design:

The semi-hexagonal outer shape resists spinning within the parent material once installed, delivering high torque-out and pull-out resistance

Reduced-head (low profile) finish:

The head height is minimized so the fastener sits flush or nearly flush with the surface, improving aesthetics, reducing snagging and enabling streamlined assemblies.

Premium stainless steel construction:

Using corrosion-resistant grades (such as A2/A4 stainless steel) ensures suitability for harsh, outdoor, marine or industrial environments. 

Reliable threaded connection:

Designed to provide strong internal threads in materials that may be too thin, soft or otherwise unsuitable for conventional tap-and-bolt solutions.

Space-saving installation:

 Because of the reduced head and anti-rotation body, this insert nut is perfect for assemblies where clearance is limited or a flush surface is required.

Technical Specifications:

• Body Style: Semi-hex (half-hex) outer profile
• Head Style: Reduced-profile (low head)
• Material: Stainless steel (A2/A4) or other specified alloys
• Installation Hole: Pre-drilled hex or keyed hole to match body shape
• Application Materials: Thin sheet metal, aluminium, composites, plastics (with proper backing)
• Performance: High torque-out and pull-out resistance; anti-spin under vibration and mechanical load.
• Finishes: Passivated, electropolished or as per customer specification

Applications

The Insert Nut Semi Hex Reduced Head is highly versatile and finds use in a wide variety of industries and applications:

• Automotive & transportation: Exhaust system mounts, chassis brackets, dashboard assemblies, infotainment housings
• Electronics & enclosures: Sensitive instrument cases, HVAC panels, server racks where flush surfaces and reliable threads matter
• Industrial machinery: Equipment panels, thin-wall metal components, fixtures where space is limited
• Metal fabrication & sheet-metal assemblies: Where standard nuts cannot be used and a flush appearance or minimal protrusion is required
• Marine / outdoor / corrosive environments: Thanks to stainless-steel construction, the insert nut performs well in coastal, salt-spray or humid conditions
