Engineered for high-load assemblies and corrosive environments, our carbon-steel custom fasteners deliver tensile strengths up to 800 MPa while remaining cost-effective. Every item is manufactured from certified low- or medium-carbon grades and can be supplied plain or with a wide range of protective finishes.

Available Carbon-Steel Grades

• AISI 1018 – excellent weldability and case-hardening response
• AISI 1022 – higher manganese for increased core hardness
• AISI 1038 / 1045 – quench-and-temper capable for Grade 8.8–12.9 performance
• SAE J403 10B21 – ideal for cold-forged bolts and screws
• Q235 / C45 equivalent – common for structural pins and rivets

Head Styles & Drive Types

• Hex head, flange head, button head, countersunk head, T-head, or custom forged head
• Internal drives: Phillips, Pozi, Torx®, hex socket (Allen), square, spline, or security pin-in-Torx
• External drives: hex, bi-hex, 12-point, knurled, or ribbed for plastic insertion

Technical Specifications

Size Range: Available in a wide range of sizes, from small to large diameters, to fit various applications.
Custom Dimensions: Lengths, diameters, and thread lengths can be customized to meet specific project requirements

Secondary Features

• Under-head serrations, captive washers, nylon patches, pellet or pellet-plus prevailing torque elements
• Drilled heads for safety wire, split-pin holes, or ball-detent grooves
• Knurls, grooves, flats, or wrenching squares for anti-rotation
• Stepped diameters, shoulders, or reduced shanks for weight savings

Packaging & Logistics

• Bulk in poly-bags + VCI paper for ocean shipment
• Small-box kitting (customer part numbers & bar-codes) for assembly line feeding
• Cartons or steel drums on ISPM-15 pallets, stretch-wrapped and strapped
• Typical lead time: 3–5 weeks ARO for new custom design; 2 weeks for repeat orders
