从India供应商批发进口Allen Bolt — FOB条款

The Allen bolt, or hex socket head cap screw per DIN 912, is a precision fastener with a cylindrical head and internal hexagonal drive recess. KPS Metal Components supplies these in stainless steel 304 and carbon steel grades 8.8 through 12.9, covering both corrosion-resistant and high-strength structural applications. The internal hex drive permits high-torque tightening with reduced head height compared to conventional hex head bolts, making it suitable for recessed or counterbored installations where external wrench access is restricted.

Material selection determines service environment suitability. Stainless steel 304 offers standardized chemical composition with 18 percent chromium and 8 percent nickel minimum, providing resistance to oxidation and mild chemical exposure. Carbon steel grades 8.8, 10.9, and 12.9 denote increasing tensile strength and yield ratios per ISO 898-1, with 12.9 requiring quenched and tempered alloy steel to achieve its 1,200 MPa minimum tensile strength. The socket geometry must conform to ISO 4762 or DIN 912 tolerances to prevent cam-out under torque; verify with KPS Metal Components whether their tools meet these dimensional standards and whether thread classes are 6g or 6h as applicable.

KPS Metal Components is based in Chennai, Tamil Nadu, India, specifically in the 600048 postal area. The company holds a harbor trust tier on the platform, indicating basic listing verification without extensive third-party validation. The response rate is recorded at 0.00 percent with zero average response hours, so direct engagement through alternative channels may be necessary to establish commercial terms. The listing emphasises DIN 912 standard compliance and multi-grade material availability without claiming specific manufacturing certifications or test house accreditations.

The supplier's profile positions KPS Metal Components as a fastener specialist serving machinery, automotive, and structural assembly sectors. No factory ownership, production capacity, or specific client references are stated. Buyers should treat initial orders as qualification transactions, requesting material test certificates and dimensional inspection reports to validate claims of grade 8.8 through 12.9 conformance. Chennai's established engineering base provides logistical advantages for sea export through Chennai Port or air freight via Chennai International Airport, though the supplier must confirm their actual export documentation capability.
