| Description | N/A 0-80 x 1/8 Alloy Steel Socket Head Cap Screw is suited to assemblies that need an alloy steel cap screw for clamp load, service access, and compact installation. With a 0-80 thread and 1/8 in. length, it fits counterbored mounting points where size interchangeability matters. Selected for engineering departments, power transmission, and maintenance repair, it gives maintenance teams a searchable alloy steel socket screw callout. Alloy steel supports strength-focused fastening where clamp load and repeatable assembly are important. The technical highlight block below retains the verified head diameter, head height, body diameter, and hex key data. Technical Highlights Material: Alloy Steel Thread: 0-80 Length: 1/8 in. Nominal Body Diameter: .060 in. Head Diameter: 0.091 in. min / 0.096 in. max Head Height: 0.057 in. min / 0.060 in. max Hex Key Size: 0.050 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote. | N/A 0-80 x 3/16 Alloy Steel Socket Head Cap Screw provides a strength-focused alloy steel socket cap screw option for mechanical assemblies requiring this exact size. The exact 0-80 x 3/16 size helps buyers align the fastener with stockroom identification and purchasing review. Applications often include manufacturing plants, maintenance repair, and maintenance shops, especially where counterbored or close-clearance mounting is required. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 0-80 Length: 3/16 in. Nominal Body Diameter: .060 in. Head Diameter: 0.091 in. min / 0.096 in. max Head Height: 0.057 in. min / 0.060 in. max Hex Key Size: 0.050 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote. | N/A 0-80 x 1/4 Alloy Steel Socket Head Cap Screw is commonly used where an Allen-style socket drive is preferred over external-wrench hardware in confined equipment layouts. This size keeps the specified 0-80 thread and 1/4 in. length visible for stockroom identification and purchasing review. Applications often include engineering departments, power transmission, and machine tools, especially where counterbored or close-clearance mounting is required. Verified head dimensions and hex key size help engineering departments check fit before ordering. This keeps the listing focused on the fastener geometry rather than broad catalog language. Technical Highlights Material: Alloy Steel Thread: 0-80 Length: 1/4 in. Nominal Body Diameter: .060 in. Head Diameter: 0.091 in. min / 0.096 in. max Head Height: 0.057 in. min / 0.060 in. max Hex Key Size: 0.050 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote. | N/A 0-80 x 5/16 Alloy Steel Socket Head Cap Screw is specified when a machine assembly needs a high-strength alloy steel socket screw with predictable head and drive geometry. The exact 0-80 x 5/16 size helps buyers align the fastener with repair work tied to an existing fastener callout. Common uses include maintenance shops, manufacturing cells, and power transmission, where internal hex installation helps keep the joint accessible. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. This keeps the listing focused on the fastener geometry rather than broad catalog language. Technical Highlights Material: Alloy Steel Thread: 0-80 Length: 5/16 in. Nominal Body Diameter: .060 in. Head Diameter: 0.091 in. min / 0.096 in. max Head Height: 0.057 in. min / 0.060 in. max Hex Key Size: 0.050 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote. | N/A 0-80 x 3/8 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. The 0-80 thread and 3/8 in. length support replacement sourcing without changing the specified size in high-clamping-force joints. It is frequently used in automation systems, power transmission, and precision assemblies when socket engagement is preferred over external-wrench access. Verified head dimensions and hex key size help engineering departments check fit before ordering. This exact size supports industrial hardware, repair, and production requirements.
