Ten processes. One roof.

CNC Turning
27 CNC lathes turning studs, bolts, nuts and machined components from ¼ in. to large-diameter bar.

Swiss-Type Turning
Sliding-headstock lathes hold small-diameter bar at the cutting tool.

CNC Milling
Multi-axis milling for hexagons, flats, slots, flanges and the non-standard geometries that come in on customer drawings.

Polygon Turning
A geared polygon cutter forms hexagons, squares and flats on a dedicated polygon turning machine.

Thread Rolling
Threads formed by displacing metal rather than cutting it.

Die-Head Thread Cutting
Single-point and die-head threading for large diameters, special pitches, tapered and left-hand threads.

Hydraulic Press
Internal hex sockets and drives broached into socket screws, set screws, plugs and custom fasteners.

Automatic Band Sawing
Numerically controlled saws cut certified bar to length around the clock, feeding the lathes without an operator at every machine.

Dot-Pin Marking
Every part is marked with its grade symbol, manufacturer's mark and heat identity.

Laser Marking
Fiber-laser marking of maker's marks, grade symbols and heat numbers.
Heat treatment, plating, hot-dip galvanizing and PTFE coating are handled through our approved Houston processors and certified with the parts.

From drawing to dispatch, under one roof.
- 01
Quotes in 24 to 48 hours
Send a drawing, a spec or a part number. Our estimators review material, thread form, coating and certification, and every quote goes back within 24 to 48 hours.
- 02
Certified material
Bar is pulled from our own stock of domestic and Western European material, each length traceable to its heat and mill certificate.
- 03
Machine and thread
Turned, milled, rolled or cut on the shop floor in Houston — heat treated and tempered after threading where the specification demands it.
- 04
Inspect and certify
Dimensional inspection, hardness and tensile testing per lot, PMI and Charpy on request, with an EN 10204 3.1 report on every order.
- 05
Mark and dispatch
Dot-pin marked, bagged, boxed, labelled and shipped — same day on hot-shot orders, 24 hours a day, 7 days a week.
Certified from heat to hand-off.
Every fastener we make starts as certified bar and leaves with its paperwork: the heat number, the chemistry, the mechanical test results and the grade marking that ties them together. Our quality system has been registered to ISO 9001:2015 since 2020, and it governs estimating, purchasing, manufacture, inspection and shipping alike.
- EN 10204 3.1 material test report on every manufactured lot; 3.2 third-party witness on request
- Tensile, hardness and proof-load testing per lot; 100 percent hardness on NACE grades
- PMI, Charpy impact and intergranular corrosion testing through approved laboratories
- Dot-pin grade and heat marking for part-level traceability
- Customer certificate portal for downloading MTRs by order

What fasteners do you manufacture?
Studs and stud bolts, hex and heavy hex bolts, socket head cap screws, set screws, nuts, washers, U-bolts, pins and machined components — to ASTM, ASME and API standards or to your drawing, imperial or metric, from ¼ in. to large diameters.
Which material grades do you stock?
ASTM A193 B7, B7M and B16, A320 L7 and L7M, A194 2H and 7 nuts, 304 and 316 stainless, 17-4 PH, duplex 2205 and super duplex, Inconel 625 and 718, Monel, Hastelloy and Nitronic, plus brass and bronze. Every grade has a data sheet on our materials pages.
Can you supply material certificates?
Yes. Every manufactured lot ships with an EN 10204 3.1 material test report showing heat number, chemistry and mechanical properties. 3.2 third-party witness, PMI, Charpy impact and NACE compliance statements are available on request, and customers can download certificates from our certification portal.
How fast can you turn an emergency order?
Our hot-shot service runs 24 hours a day, 7 days a week. Standard studs, bolts and nuts in stocked grades can ship the same day; machined parts to a drawing are typically a few days depending on material and heat treatment.
Do you make NACE MR0175 sour-service bolting?
Yes. B7M, L7M, 2HM and 7M are hardness tested on every piece to the 22 HRC limit, and we supply duplex, super duplex, Inconel 718 and Monel K-500 fasteners for CRA applications with the supporting certification.
Are you ISO 9001 certified?
Yes. Innovation Fasteners has been registered to ISO 9001:2015 since 2020 (INTERCERT certificate IC-QM-2010035) for the manufacture and distribution of high performance precision fasteners and machined components.
