Import Cylinder Head Bolts — Buy in Bulk from Supplier in Turkey

Cylinder head bolts from Sarfim Otomotiv are precision-engineered fasteners designed for securing cylinder heads to engine blocks in internal combustion engines. These bolts are manufactured to withstand extreme thermal and mechanical stresses, ensuring consistent clamping force under high-pressure conditions. The supplier’s listing highlights corrosion resistance and compatibility with multiple engine models, with sizes tailored to diverse industrial and automotive applications.

The bolts are typically produced from high-grade alloy steels such as SAE J429 Grade 5 or Grade 8, which provide the tensile strength and fatigue resistance required for heavy-duty use. Standard surface treatments include zinc plating or black oxide coatings to enhance durability in corrosive environments. Thread precision is critical, with typical tolerances of ±0.1 mm to prevent loosening under vibration, a common requirement in automotive and machinery standards like DIN 931 or ISO 4017.

These components are primarily used in automotive manufacturing, engine repair, and industrial machinery maintenance, where reliability under thermal cycling is non-negotiable. Buyers typically source them in bulk with packaging options such as cartons or pallets, and trade terms like FOB Istanbul or CIF are common. Verification of material certificates and torque specifications is advised before large-scale orders, as these directly impact engine integrity and longevity.

Sarfim Otomotiv is based in Istanbul, Turkey, with an operational address in Iems Tebrizi Mahallesi, Lefkeli Soka, Konya. The supplier is classified as an imported tier provider, indicating a focus on cross-border trade. The trust tier is marked as harbor, which reflects a baseline level of verification but does not include additional signals like response rate or average response time, both of which are currently recorded as zero.

The company specializes in automotive parts, including cylinder head bolts, and operates within Turkey’s industrial supply chain. While the listing does not provide details on certifications, production capacity, or client history, the address and tier classification suggest a structured approach to export-oriented manufacturing. Buyers are advised to confirm specific capabilities and documentation directly with the supplier before proceeding with orders.
