Yes. The MSA 816651 Skullgard Protective Cap is purpose-built for hot, demanding industries like steel mills and smelting foundries. It withstands radiant heat loads up to, but not exceeding, 350°F (176°C) thanks to its phenolic (resin-impregnated) shell, where standard polyethylene hard hats can soften or deform. It meets ANSI/ISEA Z89.1 Type I, Class G, has a smooth crown for MSA welding equipment, and uses the Swing Ratchet suspension. It ships with free shipping from Industrial Safety Products.

The MSA 816651 Skullgard withstands radiant heat loads up to, but not exceeding, 350°F (176°C). This high heat tolerance comes from its phenolic construction — a resin-impregnated shell rather than the molded polyethylene used in most hard hats — which is why the Skullgard line is a long-standing standard for steel mills, foundries, and other high-temperature environments where ordinary hard hats can soften.

The MSA 816651 Skullgard Protective Cap meets or exceeds ANSI/ISEA Z89.1, Type I, Class G. Type I certifies protection against top (crown) impact, and Class G (General) provides limited electrical protection, proof-tested to 2,200 volts under the standard. It is a cap-style hard hat with a phenolic shell, the Swing Ratchet suspension, and fits standard hat sizes 6½ to 8.

Only for limited voltage. The MSA 816651 Skullgard is Class G (General), which under ANSI/ISEA Z89.1 is proof-tested to just 2,200 volts — suitable for low-voltage incidental contact, not high-voltage electrical work. It is also Type I, so it protects against top impact only, not lateral impact. For high-voltage electrical hazards, choose a Class E (20,000-volt) helmet instead; the Skullgard's core strength is radiant-heat resistance, not electrical protection.

The Swing Ratchet is the ratcheting suspension built into the 816651 Skullgard cap. It uses a knob at the back of the head that you turn to ratchet the fit tighter or looser, letting you dial in a secure hold quickly and one-handed. Paired with the cap's phenolic shell and smooth crown, it keeps the helmet stable during work in steel mills, foundries, and other high-heat environments.

Both are Type I, Class G Skullgard hard hats with the same phenolic shell and 350°F (176°C) radiant-heat resistance. The 816651 is the cap style: a low-profile front brim with a smooth crown for MSA welding equipment, lighter and less obstructive in tight spaces. The full brim version adds a brim all the way around for extra sun, spark, and drip protection on the ears and neck. Choose the cap for a lower profile and welding-gear compatibility; choose the full brim for all-around coverage. Both are available from Industrial Safety Products.

Yes. The MSA 816651 Skullgard is a standard size that fits hat sizes 6½ to 8, adjusted with the Swing Ratchet suspension — a knob at the back you turn to ratchet the fit tighter or looser, one-handed. This standard range covers most adult head sizes in a single helmet; MSA's Skullgard cap line also offers a large size (7 to 8½).

Yes. The MSA 816651 Skullgard cap has a smooth, non-slotted crown designed for easy use of MSA welding equipment such as cap-mounted welding shields and accessories. Combined with its 350°F (176°C) radiant-heat resistance and phenolic shell, it's well suited to welding, steel smelting, and other high-heat operations where sparks and radiant heat are a concern.

Yes. The MSA 816651 Skullgard cap ships with free shipping from Industrial Safety Products, and optional custom logo imprinting and striping are available. Logo printing is priced per location: $6.60 per location for a single color, or $10.90 per location for up to 4 colors, on up to four locations (front, back, right, and left sides). It requires a minimum order of 20 hard hats, and a set-up fee may apply; orders under the 20-unit minimum ship as non-logo items.

The MSA 816651 Skullgard is built for extreme heat, unlike a standard polyethylene hard hat. Its phenolic (resin-impregnated) shell withstands radiant heat up to 350°F (176°C), where ordinary hard hats can soften. It adds a smooth, non-slotted crown for MSA welding gear and a one-handed Swing Ratchet suspension. It meets ANSI/ISEA Z89.1 Type I, Class G. Built for heat resistance, it's a go-to for steel, foundry, and welding work, and ships free from Industrial Safety Products.
