A193 A914 B8 A453 A286 Astm Aisi Ansi Knurled Hexagon Socket Low Head Short Head Cap Metal Screw Din7984

This knurled low head hex socket cap screw combines low head (DIN7984) , knurling, and high-performance alloy materials. Materials include ASTM A193/A914 B8 (304 stainless steel) and ASTM A453 Grade A286 (high-temperature superalloy) , with corresponding AISI/ANSI grades. The knurling under the head aids hand starting. The low head height conforms to DIN7984, suitable for space-limited applications. A286 retains high strength up to 650°C with excellent oxidation resistance. B8 offers general stainless corrosion resistance. The short head design reduces overall screw length, ideal for thin sheets or compact structures.

Aero-engine accessory brackets – A286 high-temperature resistance, low head avoids interference.

Gas turbine casing access covers – knurling for gloved operation.

High-temperature furnace sensor mounting – short head plus knurling for quick removal.

Chemical valve limit switches – B8 corrosion-resistant.

Racing exhaust manifold heat shields – A286 resists thermal shock.

High-performance alloys – A286 for high temperature, B8 for corrosion resistance.

Low head + knurling – space saving plus manual handling ease.

ASTM compliance – material traceability.

Short head design – reduced overall height for compact assemblies.

Multi-standard compatible – ASTM/AISI/ANSI for export requirements.
