Inconel 601 Socket Cap Screws — Specifications & Dimensions
Inconel 601 Socket Cap screws are externally threaded fasteners typically driven into a tapped hole or self-tapped material. TorqBolt manufactures Inconel 601 Socket Cap screws per ASME B18.3 (socket products), ASME B18.6.3 (machine screws), DIN 912 / 7991 / 6912, and ISO 4762 / 10642, in metric M3–M48 and imperial 0–1/2".
Drive Types
Hex socket (Allen) — ASME B18.3 / DIN 912, primary for high-torque industrial use
Inconel 601 Socket Cap screws are available in cap (cylindrical), button (low-profile dome), countersunk / flat (82° or 90°), pan, fillister, truss, and shoulder configurations. Countersunk per DIN 7991 with 90° head angle is standard for metric; 82° per ASME B18.6.3 for imperial.
Thread & Length
Inconel 601 Socket Cap screws use full-thread or partial-thread (length-under-head) configurations. Machine screws are typically full-thread; cap screws use partial thread for grip control. Threading per ASME B1.1 (UNC/UNF) or ISO 965 (metric coarse/fine), Class 2A or 6g default. Length-under-head is measured from the bearing surface for hex/cap, from the largest face for countersunk. Custom lengths quoted to drawing.
Specialty Screws
TorqBolt produces Inconel 601 Socket Cap set screws (cup-point, cone-point, dog-point, flat-point, hex-socket DIN 913/914/915/916), shoulder screws (precision-ground shoulder for pivot applications), and self-tapping screws (Type AB, Type 25). All certified per EN 10204 3.1 / 3.2 with optional NACE MR0175 sour-service compliance.
Inconel — Nickel-Chromium Superalloys
Inconel alloys are nickel-chromium-based superalloys engineered for service where standard stainless steels cannot survive. The Inconel family combines high-temperature strength (typically retained up to 700-1100°C depending on grade) with outstanding oxidation and chloride-pitting resistance.
The most widely specified grade is Inconel 718, an age-hardenable Ni-Cr-Fe-Mo-Nb composition strengthened by γ' (Ni₃Al,Ti) and γ'' (Ni₃Nb) precipitates after solution + double-age heat treatment per AMS 5662 / 5663. Inconel 625 is solid-solution strengthened by Mo+Nb, supplied in the as-annealed condition, and weldable without post-weld heat treatment. Inconel X-750 uses Ti+Al precipitation hardening for spring + bolt applications to 700°C. Inconel 600 / 601 are general-purpose grades for furnace and heat-exchanger fasteners.
Typical specifications: ASTM B637 (forged bar), AMS 5662/5663 (rod/bar), ASTM B446 (625 bar), DIN 17752/17754 (round/forged). NACE MR0175 / ISO 15156 sour-service envelopes available on most grades when supplied in the correct heat-treat condition. PREN values for chloride pitting resistance typically exceed 50 across the Inconel range.
