Product Description
A36 Introduction
ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for
grinding,punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018,thus enabling ASTM A36 to bend more readily than C1018. Normally, larger diameters in ASTM A36 are not produced since C1018 hot roll rounds are used.

A36 Fastener Wing Bolts Introduction
Wing Bolt is a special hand-tightened fastener featured with two integrated wing-shaped ears on the bolt head. Different from standard hex bolts, it allows quick manual tightening and loosening without any wrenches or professional tools, greatly improving assembly and disassembly efficiency. Manufactured from high-quality carbon steel, stainless steel and brass materials compliant with international standards, wing bolts deliver stable structural strength, excellent surface hardness and reliable deformation resistance. The ergonomic wing design provides large gripping force and uniform stress distribution, ensuring firm locking and stable connection. With outstanding anti-corrosion, wear-resistant and long-lasting performance, these bolts are widely applied in mechanical equipment adjustment, furniture assembly, electrical enclosures, mold fixtures, testing instruments, ventilation systems and daily industrial quick-fixing scenarios. Wing bolts are essential standard fasteners for frequent disassembly,temporary fixing and flexible positioning applications.

A36 Fastener Wing Bolts Product Processing
1.Raw Material Inspection & Blanking:
Adopt premium carbon steel materials that conform to international fastener standards. Strictly verify material chemical composition, mechanical properties, surface flatness and internal metallographic structure to exclude cracks, inclusions and oxide flaws. Qualified raw materials are precisely cut into fixed-length blanks in accordance with product specifications, providing stable and consistent raw material conditions for subsequent integral forming.
2.Surface Pretreatment & Integral Forming:
2.Surface Pretreatment & Integral Forming:
Implement standardized surface pretreatment including degreasing, decontamination and lubrication to eliminate surface oil stains and oxide layers, ensuring smooth forming and clean surface texture. Adopt precision cold heading and die forging technology to complete one-piece integral forming of wing head, transition position and bolt rod. The integral molding process delivers compact internal structure, unified stress distribution and outstanding structural stability without splicing gaps.
3.Trimming, Shaping & Thread Rolling:
3.Trimming, Shaping & Thread Rolling:
Remove residual burrs, flashes and sharp edges on the wing surface, head and rod body. Conduct precise shaping and symmetry calibration to standardize wing radian, flatness and overall geometric dimensions for stable gripping performance. Adopt high-precision thread rolling process to form standard threads with accurate pitch and complete tooth profile, ensuring smooth assembly, tight meshing and reliable locking effect during frequent manual disassembly and fastening.
4.Heat Treatment & Stress Relief:
4.Heat Treatment & Stress Relief:
Perform customized heat treatment according to different material grades, including quenching and tempering for carbon steel products and stress relief annealing for stainless steel and brass models. This procedure thoroughly eliminates residual internal stress generated during cold forming, stabilizes structural hardness and mechanical toughness, and effectively improves tensile resistance, deformation resistance and fatigue resistance, avoiding structural failure in long-term repeated use.
5.Surface Treatment & Full-Range Quality Inspection:
5.Surface Treatment & Full-Range Quality Inspection:
Complete professional surface treatments such as electro-galvanizing, hot-dip galvanizing, blackening and passivation to strengthen anti-rust, anti-corrosion and wear-resistant capabilities. Carry out comprehensive quality inspection covering dimensional tolerance detection, wing symmetry test, thread precision calibration, hardness testing, surface defect screening and assembly performance verification, ensuring all products comply with industrial fastening and application standards.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Mark qualified wing bolts with complete specifications, material grades, execution standards and production batch information. Finish accurate sorting and counting, and adopt dust-proof, moisture-proof and anti-collision standardized packaging to protect thread teeth and wing structures from damage. All finished products are classified and stored in standardized warehouses and delivered after strict final inspection.
