Brass Hex Head Screws About

BRASS HEX HEAD SCREWS - COMPLETE DESCRIPTION

Product: Brass Hex Head Screws / Bolts (ISO 4017 / DIN 933)

Alternative Names: Hexagon Head Bolts, Hex Cap Screws, Six-Sided Head Screws, Hex Head Machine Screws, Hexagonal Bolts

Material: High-grade brass alloy (CuZn 60/40)

Finish: Polished golden brass (Natural, Lacquered, Nickel-plated, Chrome-plated options available)

Head Type: Six-sided hexagonal head with flat top surface, wrench-driven

KEY FEATURES:

Hexagonal Head Design: Six flat sides for secure wrench or socket grip, prevents slipping during installation High Torque Capacity: Hex head allows greater tightening force compared to socket head screws Corrosion Resistant: Brass composition ensures excellent performance in marine, humid, and outdoor environments Non-Magnetic: Suitable for electronic equipment and sensitive instrumentation Electrical Conductivity: Can be used for grounding and bonding applications Aesthetic Appeal: Attractive golden brass finish for decorative and visible fastening applications Easy Installation: Standard hex wrench or socket tool - no special tools required Durable Material: Long-lasting performance with minimal maintenance Precision Threads: Machine-cut threads for accurate engagement and secure fastening Versatile Applications: Suitable for wood, plastic, soft metals, composites, and various materials

TECHNICAL SPECIFICATIONS:

Material Composition: CuZn brass alloy (Cu 60-65%, Zn 35-40%) Surface Treatment: Polished/Bright golden brass finish Thread Type: Machine thread, uniform pitch, full or partial thread Head Style: Hexagonal (6-sided) with flat top and chamfered edges Drive Type: External hex (wrench or socket driven) Standards Compliance: ISO 4017, DIN 933, ANSI B18.2.1, BS 1768

HEAD DESIGN SPECIFICATIONS:

Head Shape: Hexagonal (6 flat sides) with flat top surface
Head Height: Standard height approximately 0.7 diameter
Across Flats (AF): Standard wrench size for each diameter
Across Corners: Diagonal measurement for socket clearance
Chamfered Edges: Smooth edges for easy installation and professional appearance

AVAILABLE SIZES:

Metric Sizes (ISO 4017 / DIN 933):

Diameter: M2, M2.5, M3, M4, M5, M6, M8, M10, M12, M16, M20
Length: 5mm to 100mm (varies by diameter)
Wrench Size (AF): 4mm to 30mm (proportional to shaft diameter)

ADVANTAGES:

High Torque Application: Hex head design allows maximum tightening force with standard tools Universal Tool Compatibility: Works with standard wrenches, sockets, and adjustable spanners Excellent Corrosion Resistance: Brass naturally resists rust, oxidation, and marine environments Non-Sparking: Safe for use in explosive or flammable environments Aesthetic Golden Finish: Attractive appearance for visible applications and decorative hardware Electrical Conductivity: Ideal for grounding, bonding, and electrical connections Non-Magnetic Properties: Won't interfere with electronic equipment or magnetic fields Easy Inspection: External hex head allows visual verification of tightness Durable & Long-Lasting: Brass resists wear, galling, and thread damage Temperature Resistant: Maintains properties in wide temperature range (-200C to +200C) Chemical Resistant: Withstands exposure to many chemicals, oils, and solvents Recyclable Material: 100% recyclable brass for environmental sustainability

SURFACE FINISH OPTIONS:

Natural Brass (Polished): Standard golden finish with bright, reflective surface
Lacquered Brass: Anti-tarnish clear coating preserves shine and prevents oxidation
Nickel Plated: Silver appearance with enhanced corrosion resistance
Chrome Plated: Bright chrome finish for decorative and high-wear applications
Antique Brass: Aged/oxidized finish for vintage or rustic aesthetic
Black Oxide: Dark finish for contrast or stealth applications
Zinc Plated: Additional corrosion protection with silver-gray appearance
Custom Finishes: Consult for special color or coating requirements

INSTALLATION GUIDELINES:

Pilot Hole: Drill pilot hole slightly smaller than screw diameter (approximately 85-90% of major diameter)
Clearance Hole: For through-hole applications, drill clearance hole slightly larger than shaft diameter
Wrench Selection: Use correct size wrench or socket that fits hex head snugly (across flats measurement)
Alignment: Ensure screw is perpendicular to surface for proper thread engagement
Tightening: Apply steady, even pressure - avoid over-tightening which can strip threads or damage material
Torque: Follow recommended torque values (see table below) for optimal clamping force
Thread Engagement: Minimum thread engagement should be 1.5 diameter for steel, 2 diameter for softer materials
Lubrication: For high-torque applications, light lubrication on threads can prevent galling

RECOMMENDED TORQUE VALUES:

Size	Torque (Nm)	Torque (lb-ft)	Wrench Size (AF)
M3	0.5-0.7	0.4-0.5	5.5mm
M4	1.0-1.4	0.7-1.0	7mm
M5	2.0-2.8	1.5-2.1	8mm
M6	3.5-5.0	2.6-3.7	10mm
