Hex Socket shoulder screw, Stainless & Alloy Steel Metric Inch Fasteners for Mold Fixture Automation Custom Available

🎯 We are a professional industrial fastener manufacturer focusing on standard and customized shoulder screw development and manufacturing. Our shoulder screw series targets precision mold, tooling fixture and automation machinery industries, solving common industry pain points including positioning offset and loose connection from ordinary machine screws. Different from conventional fasteners, our precision shoulder screw integrates positioning shoulder and fastening thread into one part to realize dual functions of fixed locking and movable rotation, forming obvious differentiated advantages versus peer suppliers. We keep bulk standard shoulder screw in stock meanwhile produce non-standard custom shoulder screw per clients’ CAD drawings, covering complete metric and inch specification systems to satisfy diversified industrial assembly demands.

📊 Our complete shoulder screw product line is sorted into metric specification group and inch specification group:

• metric shoulder screw: Thread range from M1.6 to M16, customizable shoulder diameter 2mm–30mm and shoulder length 3mm–80mm, manufactured following ISO7379 industrial standard.
• inch shoulder screw: UNC and UNF thread ranging from #2 up to 1/2 inch, produced under ASME B18.3 specification requirements.

Available raw material options: SUS304, SUS316, Grade 8.8/10.9/12.9 alloy carbon steel. All parameter indexes can be revised for tailor-made custom shoulder screw upon buyer’s personalized requirement.

⚙️ Our industrial-grade shoulder screw has gained wide popularity across downstream precision manufacturing industries:

1. Mold manufacturing field: mold shoulder screw acts as limiting bolt and locating pin for stamping mold and plastic injection mold to control mold opening stroke and avoid plate shifting during production.
2. Tooling fixture industry: fixture shoulder screw serves as rotating pivot component for all kinds of processing fixture and testing jig.
3. Automation equipment field: automation shoulder screw is widely equipped on conveying equipment, robotic arm connecting structure and small precision transmission machinery.

Practical cooperation case: We provide stable monthly bulk supply of customized metric shoulder screw for multiple domestic automation manufacturers, helping partners replace expensive imported fasteners and cut accessory procurement cost effectively.

💡 Most machinery purchasers encounter frequent troubles including mismatched dimension, short anti-corrosion lifespan and long production lead time when purchasing generic screws, and our full-series shoulder screw brings targeted one-stop solutions. High-precision machining of our shoulder screw eliminates assembly clearance error and reduces post-installation maintenance expense of end equipment. In-stock standard shoulder screw supports immediate small-batch shipment to shorten your procurement cycle, while bulk customized order of custom shoulder screw enjoys factory-direct preferential unit price to optimize your purchasing budget. Every batch of our outgoing shoulder screw goes through dimension inspection, hardness testing and salt spray test to verify product stability with actual test data.
